I understand there is a 1.8mm spacer, but I can't find it online, im only finding Shimano spacers.
My other question is, if I put a spacer below the cassette, what happens to the top 3 loose cogs, since the splines don't run all the way to the top, do you just tighten it down, and they don't have to engage with the splines?

You’ve got an HG cassette, not XD. I don’t know why the HG freehub (the loose one in the foreground) shell is marked XD.
A standard 1.85mm cassette spacer will work on either XDR or 11s road free hub bodies. There is no XDR specific spacer.
Also it looks like your Shimano HG free hub body has “XD” stamped into the splines. That free hub body is not an XD free hub body, it’s a Shimano free hub.
What is the exact model of cassette are you are trying to mount up here?
For an XD cassette to fit on an XDR hub, you need a 1.85mm spacer. The Shimano spacers should fit…pretty sure that’s what I have on one of my hubs. Here’s a [sample one](https://project321.com/products/1-85mm-cassette-spacer).
Regarding the cassette in the picture, is that an 11 speed? Every SRAM 12 speed cassette I’ve seen is one piece in the smaller gears.
Ya that’s not an xd driver that’s shimano he driver
XD/XDR cassettes don’t have loose cogs, the lock ring is integrated into the cassette itself. What you have there is a HG freehub body and a HG cassette, like the other commenter said, not sure why it says XD on that HG freehub. You can either get an HG freehub body that is made for your wheels if there is one (looks like bontrager wheels?) or a new 12s XD casette. Cheaper options is probably the freehub body, but could be an excuse to upgrade to something lighter with the same ratios or wider ratio since the smallest cog on an XD is 10t instead of 11t on HG.
