Modify code to send /32 in EDNS0 instead of /24 subnet

[miladtempaccount]

Hi there, I want to send /32 ( clientip ) instead of /24 subnet in eds0 or ecs, I have my own upstream server and there would be no issues, just tell me how can I do it ?

I didn't found it on the code, where should I edit on the code base ?

Thanks in advance
