1x conversion on 9spd hardtail

Hi,
I have an aluminum Gary Fisher hardtail bike, I'm presuming it's from the 2000's, made in the usa, nice bike. It's a 9 speed with a 175 triple crankset. On my road and touring bikes I run a 165mm crank, so the 175 feels way way too big, because well, it is too big for me. I have a 165 Sugino touring triple I could throw on there, but I thought, why not a 1x conversion.
I've never done one of these, and looking at the options, it seems that the current entry level Shimanos all have some level of 'boost', which I don't think I would want since it's a standard 135mm hub.
Would this work? https://www.modernbike.com/sram-nx-g...old-separately
Any caveats I would need to be aware of?
I probably will not do any offroad with it, mostly gravel.
Thanks!
Jon

I would try it with the triple first.
Remove the FD and see will you like a single up front.
I have been trying it and it works but it really isn't ideal for me. So now the FD is going back on and the experiment is done.

Definitely try the triple you have; be aware that you may need a different-length bottom bracket for the new crankset. I run triples on all of my bikes, I would not like being stuck with a single up front. But I am old and set in my ways.

A 1X requires a wide range cassette.
IF you ride in the flats, you may have gears (11 & 30+T cogs) you never use + wider steps between gears. Using a closer spaced cassette for the road means you don't have the low bail out gear for the hills.
Both my bikes have 165mm "mountain" triples. FSA "something" for about $35 on ebay.

The crank you posted should work fine. Note you'll need a chainring if it's not included (narrow wide if you go 1x) and a matching bottom bracket. You'll need to figure out how big a chainring and what cassette is ideal for your intended riding.
