Does anyone know how to make a Free Software DRM that can fullfill the
DRM function?

Step 1. study the code
Step 2. modify the code
Step 3. Enjoy your civil rights limited by laws written by idiots with
deep pockets.

I'd say any Free Software DRM is snake oil, but I can be proven wrong.

Then it's not Free Software, since you will not hanve the freedom to
modify it (hence, oxymoron of "Free Software DRM").
