Trace flag 4136 can improve the performance in Dynamics AX--How to test that before and after the change

Hi Friends
I have 5 TB DB for AX.
And I know parameter sniffing default behavior may cause seek to scan for parametrized stored procedures.
And now I want to use T4136 flag to prevent this as per AX best practice.
How do I test it in production server to show customers before and after the change.

Regards,
Anjan
