2x10 XO crank to 1x?

I have a buddy that gave me some carbon XO cranks. They are in 2x10 setup though. I want to put them on my Rocky Mountain Growler that currently has a 1x10 Shimano deore setup. Can I get a 1x chainring that will work with my 1x10 boost setup? And his bike had a PF30 BB but mine is threaded. Will the spindle work or will I need to get a different one? What BB will work?

Wondering if this will work?

If I remember right they are not a direct mount crank. So you need a chainring with a super rare BCD. Like almost impossible to find. Wolf Tooth has them on their site but I have never seen them in stock. And then you have the PF30 thing. I would say thanks but no thanks and buy your self a nice set of alloy cranks that fit and chainrings are available for.

If it's a 2x10 BB30/PF30 crankset you should be able to remove the spider and replace it with a newer sram direct mount 1x ring.

The spindle will be too short to work with a threaded BB and likely the wrong diameter. However the older BB30/PF30 Sram crank arms can be removed and used with a 30mm Raceface cinch spindle. This allows you to use the cranks with 30mm threaded BBs.

Not my video but very helpful:
