EFI partition always mounted - How to flag as ESP?

On my desktop Ryzen Hackintosh, I have the EFI partition always mounted - it's visible in Windows AND in macOS.

I had some issues getting an EFI partition made, due to this being my first hackintosh. So I created one manually, it's been working fine since early January, but my EFI partition is always there, no need for mount EFI.

Is there a way I can flag it so the partition isn't visible? I read someone mention using a Gparted live USB for it, I'd like to do it through native windows/Mac tools but if not, that's fine too, just don't know the steps to do that.
