Hey @Rishi-source Thanks a lot for letting me know!!
Actually I have raise a different PR for NVD Anchore Pipeline and that one is also under review altho I have made a separate branch for both the PRs but due to unmerged PR those changed files are also shown here.

Do not worry about your unmerged PR while making a new PRs if both the pull req. have unrelated changes (changes which are not conflicting) then github will provide a update branch option whenever new changes are merged.
