I have checked this in a Win10 / Gimp 2.10.32 and it seems to work. Too many attachments, so screenshots are in the attached PDF. Two additional plugins required gegl_command.py and for_gegl.py (in the attached zip). That last one contains the gegl command saturation scale=1.2 Change that if you need more/less saturation. They go in your Gimp plugins folder.
Reference that PDF
(1) Make your adjusted color-curve and export as a file. Any old file name will do.
Use that file in the BIMP Color correction "Change color correction from settings file"
(2) Use Other Gimp procedure. Search for gegl. Use the python-fu-run-gegl entry. There are no parameters.
(3) Use Other Gimp procedure. gimp-brightness-contrast. It is deprecated but that is the one for a contrast=10 setting.
This set of operations is slow here, gegl to blame, try it out on one or two images first before setting loose on hundreds.
