Evasion technique false positive

Hi Experts,

We have a requirement to relax evasion technique checks for a specific application. Is it possible to do using an irule. We are using ASM_REQUEST_DONE event for Negative signature block relaxation. Similar way , could you please let me know the way to relax evasion technique.

when ASM_REQUEST_DONE { if { [ class match [HTTP::host] contains hostname_dg ] and [ class match [HTTP::uri] contains URI_dg ] and [ class match [ASM::violation details] contains "sig_data.sig_id signature" ] } { ASM::unblock } }
