Intel 660p not showing in Disk Utility

Hello everyone, trying to update to Big Sur, and wanted to install to another spare drive I have.

When I boot up, I don't see my 660p. Its detected in bios, and is supposed to be natively supported from what I've read.

I have nvmefix.kext, and don't think I am forgetting anything.

Any ideas or guidance will be of big help!
