How can i change the p4 profile in ecSONIC-202111, WEDGE100QS?

Dear team,

I'm using ecSONIC-202111-bfn-154 in wedge100QS.

And i'm trying to test segment routing (SRv6), but current version of p4 profile running in the switch does not support SR.

So I want to change the p4-profile, but I can't find the path where SDE is installed. 

Are there any guidelines for this?

Regards,

Seokwon.
