Can’t remove “Support for PA/PET” from PA6-GF part

I got this special filament to help print some 90 degree overhangs nicely but it’s bonded on pretty strongly to my part. Grey part is Bambu PA6-GF printed with the default profile except temp increased by 5 deg to 270, and green is Bambu Support for PA/PET printed with the default profile. Zero gap as recommended by the slicer.

Any tips for removing the filament? Access with tools isn’t great and it’s stuck on real well…

Both filaments have been dried thoroughly before printing.
