Not 100% sure i understand what you want to do....
Do you want to
a) non destructively replace a single coloured background ?
or
b) get rid of a single coloured background ?
For a) you use a layermask
for b) ofn-erase-background
https://www.gimp-forum.net/Thread-ofn-erase-background
Both techniques could be combined into one, by applying ofn-erase-background on a duplicate, then alpha selecting the erased background and applying the selection as a layermask to the original image.
Then you can delete the helper duplicate and put a background in the colour you want, behind the original image with the layermask.
