Sure you can. You can even override the T2 chip in Recovery Mode. The thing I miss on an Apple Silicon Mac is installing Windows. It was a big downside for me, so I held onto my Intel Mac until a few years ago. I used to have a tri-boot Mac Pro running Snow Leopard/Windows XP/Red Hat. Then I downgraded to an Intel iMac with macOS/Windows before my M2. I do miss the versatility of Intel Macs.
