Does it have TPM 2.0?

From reading the manual and looking at the board, I could find no mention of a TPM anything. Although it does say Windows 11 ready.

How many sata ports are usable if I populate all 5 m.2 slots on this motherobard?

The motherboard has 6 SATA 6Gb/s ports. When all M.2 slots are populated, the number of usable SATA ports may vary depending on the configuration of the M.2 slots and the specific CPU used. For detailed compatibility, refer to the motherboard's manual or the ASUS website.
