Detach Unreferenced PDFUNDERLAY

[scot-65]

Looking for some direction as part of file maintenance to detach unreferenced PDF's.

Many topics regarding DWG reference and IMAGE reference, but no PDFUNDERLAY.

DFX items:

(0 . PDFUNDERLAY)

(100 . AcDbUnderlayReference)

Should be compatible with R2024-LT.

Any help appreciated.

I browsed that thread and overlooked that particular section.
Hoping there would be a simpler answer.
Did not know the dictionary name.
