How to permanently delete default gcode files

How to permanently delete default gcode files

When I delete the gcode files (default ones supplied with printer) like Benchy from the printer, they all come back after a power cycle. I can delete the ones I upload and they stay gone, just the original ones keep coming back. Any way to stop them from coming back?

the files are stored in the following path /rom/usr/share/klipper/gcodes/

when i try to del them via ssh with a “rm” command i get a message saying I can not because they are read only. any help would be great. thank you
