Hi @Dibbu-cell, thanks for the PR but I'll be closing it:

• we don't know if we're even going ahead with Selective disabling option for N+1 warnings #4887
• the n+1 issue detection is happening on the server, so this would actually need sdk as well as sentry support
• I don't think we should be adding a completely new mechanism to the sdk unless there's a really good reason
