google cloud platform - Point only homepage to GitHub pages and use GCP web server for everything else

Question

I have an Apache Web Server running on a GCP compute instance. Currently, I have a custom domain pointing to GitHub pages using CNAMEs and A Records. How can I continue with that functionality while also redirecting any subfolders to my web server?

Desired behaviour:

example.com --> xyz.github.io [currently working]
www.example.com --> xyz.github.io [currently working]

example.com/folder/item --> File on GCP webserver
www.example.com/folder/item --> File on GCP webserver

I think it might be possible with .htaccess redirects but I believe that would cause is a certificate and domain mismatch?

Also, one other roadblock is that the folder redirect should be for every folder except /images/ as that's hosted on GitHub already.
