I don't have the M05 frame, but as far as I remember some builds the biggest was 38T with boost chainline (52mm).
Maybe someone who ride it can tell. The Airwolf YFM-026 is hard to beat with 42-44T, but the HA is 69.5
Yeah I've looked at it. Ideally HTA would be a bit slacker, but it's not a disaster as I'd use it as a drop bar gravel bike. Slack STA is more of a pain ... though again that can be remedied with a Fair Bicycle adapter. Also 10mm less BB drop than most similar frames is definitely not a positive for most use cases for this frame - bike touring excepted.
But I really wish someone would make one of the modern 67-68 HTA and 76 STA hardtails with capacity for a 44 or 46T and 100mm fork, super deep profile head tube, and IS52/IS52. It wouldn't be particularly difficult to do, with some shaping of the DS chainstay. There are so many scale clones or inspired frames, but none with bigger clearance.
