This isn’t a very good guide. There are a bunch of gottas for Proxmox and I am sure it is the same deal for XCP-NG.
Here is the official Proxmox docs:

For adding modules I personally had to switch to grub. You can switch over with Proxmox boot tool.
I’m going through it rn for Proxmox, it’s a pain in the ass.
I think it was better a tad on ESXi, but VMware stuff is a non starter for me at this point.
I still dont understand broadcom’s move except for short term profits. All the kids used to use it, and now they’re on proxmox.
I work in public sector and we’re transitioning away from VMware now, as the people we recruit know proxmox and not VMware.
Just like adobe lets the kids get away with pirating - as that builds following - VMware was giving away single-seat.
