BypassCustomPluginExecution not working on On-Premise CRM instance

Hi community,

https://learn.microsoft.com/en-us/power-apps/developer/data-platform/bypass-custom-business-logic?tabs=sdk

BypassCustomPluginExecution is not working even if I use latest version of Microsoft.crmsdk.xrmtooling.coreassembly package.

CRM INSTANCE VERSION - 9.1.14.17

PLUGIN IS STILL GETTING EXECUTED EVEN THOUGH I PASS TRUE VALUE .

CrmServiceClient.BypassPluginExecution=true:

Please help!

Is this functionality not supported on on-premise version of dynamics CRM??
