Crankset and bb size MTB

Hi,

My MTB has a pressfit 92 bottombracket and a truvativ stylo 6k. However it has a 32t. Its a XC mtb and i live in a relative flat place and will do beachracing. My frame can fit a 36t so i want to upgrade to a (preferably powermeter crank) 165mm/170mm crank with a 36t that fits my BB. What are my options? I tried to google this but its hard to find clear answers as the google advertisement AI just tries to sell me stuff lol.
