irule to select an ASM policy

Dear community,

I am trying to disable "Attack Signature" checks for a specific URL.

As I didn't find a way to do it directly via the ASM policy itself, I thought to do it like that :

Add an irule to my VS that will disable the ASM (ASM::disable), then based on my URL I want to use asm_policy_1 or asm_policy_2.

The problem is that I didn't find a command to make :

ASM::select asm_policy_1 $
ASM::enable

or something like the command "WEBSSO::select"...

Any idea on how to do it ?

Thanks
