Replacement keys for Kawai KDP90

What can I do when I can’t find replacement parts anywhere for my piano? I hate to junk it over this. I have two broken keys, D and F. I took the keyboard to the repair shop and they couldn’t find replacement parts. They tried epoxy gluing the two pieces of each key back together but they just came apart after a few weeks of use and are now totally unfixable as they cracked even worse.

I can’t find anything on the Internet for replacement keys for this keyboard. Any ideas what I can do? I’d even take off color 3d printed keys if it would prevent me from having to replace the whole keyboard.
