1. A system, comprising: a subsea chemical injection system configured to inject a chemical into a well, wherein the subsea chemical injection system comprises: a subsea choke configured to flow the chemical; anda choke trim of the subsea choke, wherein the choke trim comprises a flow path having a cross-sectional area and a length, the cross-sectional area and length are each adjustable independent from one another, and wherein the choke trim comprises: a first portion comprising a first set of concentric cylinders; anda second portion comprising a second set of concentric cylinders, wherein the first and second sets of concentric cylinders are nested relative to one another, and the second portion is configured to move axially relative to the first portion to adjust the length of the flow path. 2. The system of claim 1, wherein the first and second portions are configured to rotate relative to one another about a central axis of the choke trim to adjust the cross-sectional area of the flow path. 3. The system of claim 1, wherein each of the first set of concentric cylinders comprises a first flow port, each of the second set of concentric cylinders comprises a second flow port, and each of the first and second flow ports extends between at least one passage formed between the first and second set of concentric cylinders. 4. The system of claim 3, wherein the first and second flow ports are configured to align with one another in at least one position of the second portion relative to the first portion. 5. The system of claim 1, wherein the subsea chemical injection system comprises an actuator configured to actuate a component of the choke trim to adjust the cross-sectional area, the length, or both. 6. The system of claim 5, wherein the component comprises the second set of concentric cylinders. 7. A system, comprising: a choke trim of a subsea choke configured to flow a chemical for injection into a subsea well, wherein the choke trim comprises a flow path having a cross-sectional area and a length, wherein the cross-sectional area and length are each adjustable independent from one another, and wherein the choke trim comprises: a first portion comprising a first set of concentric cylinders, and each of the first set of concentric cylinders comprises a first flow port; anda second portion comprising a second set of concentric cylinders, wherein each of the second set of concentric cylinders comprises a second flow port,wherein the first and second sets of concentric cylinders are nested relative to one another, the second portion is configured to move axially relative to the first portion to adjust the length of the flow path, the first and second portions are configured to rotate relative to one another about a central axis of the choke trim to adjust the cross-sectional area of the flow path, each of the first and second flow ports extends between at least one passage formed between the first and second set of concentric cylinders, and the first and second flow ports are configured to align with one another in at least one position of the second portion relative to the first portion. 8. A method comprising; providing a choke trim of a subsea choke;adjusting a rotational position of a first component of the choke trim relative to a second component of the choke trim to adjust a cross-sectional area of a flow path of the choke trim; andadjusting an axial position of the first component of the choke trim relative to the second component of the choke trim to adjust a length of the flow path of the choke trim,wherein the cross-sectional area and length are each adjustable independent from one another. 9. A method, comprising; providing a choke trim of a subsea choke;adjusting a first position of a first component of the choke trim relative to a second component of the choke trim to adjust a cross-sectional area of a flow path of the choke trim; andadjusting a second position of the first component of the choke trim relative to the second component of the choke trim to adjust a length of the flow path of the choke trim,wherein the cross-sectional area and length are each adjustable independent from one another, and wherein the first position and the second position are different.
