windows 10 – I have a lot of EFI partitions on my computer. I’m trying to figure out which ones are no longer in use

This is my disk layout. I have installed/reinstalled Windows and Linux distros multiple times on this machine over the past couple years, and the EFI partition situation is getting ridiculous.

The 512GB SSD (Disk 2) is the one that originally came with the machine, and it currently does not even have an OS installed on it. I have absolutely NO IDEA if any of the EFI partitions on it are in use. This is the first machine I’ve used EFI with, so having partitions on the hard disk specifically for boot functions is still kind of confusing to me.

I know in one occasion, I clicked on Windows 10 on one of the Windows Boot Manager screens, it rebooted, and went into a different Windows Boot Manager screen with the correct entries on it. That’s the only one I want. I’m trying to free up the entire SSD on Disk 2 to install Linux onto, so ideally, I’d like to be able to remove everything on that drive, and still be able to boot into the two Windows installations I have. (Once I finally get around to backing everything up from it, one of those installations will be removed.)

So yeah, I’m just trying to identify which EFI partitions I actually NEED, and which ones I can dispose of.
