Github webhooks triggers a multibranch scan of all refs

Hi Team,

Currently we migrated to GIT HUB Enterprise version, and we are using the jenkins as CI Tools and configured Multi Branch Pipeline.
We are using Moo Repo and configured as Multibranch pipeline . In that Mono Repo we have 100 SubRepos we have .

. We have a large repository - and so many commits every day. Every time a webhook is fired from github and hits jenkins all N multibranch pipelines begin scanning ALL remote refs for the repository.having all subfolder .

can you please help us instead of scanning all sub repos , need to scan only specific sub repo only. Kindly suggest on this one .
