I'm having trouble accessing the UEFI after disabling CSM on my Gigabyte B365M-D3H motherboard. The background is that I got a TPM 2.0 module to meet the requirement for playing CS2 with Faceit. After installing it, the system recognized it in both the BIOS and Windows, but I then faced a new issue when I tried to enable Secure Boot. The BIOS instructed me to disable CSM to enable Secure Boot, but once I did that and rebooted, the system just gets stuck on the Gigabyte logo and doesn't boot. This happens until I reset the BIOS using the CMOS battery or the motherboard jumpers. I've checked that my drive is in GPT mode, reinstalled Windows 11 multiple times, and my BIOS is up to date. I've also tried switching graphics cards and using integrated graphics, but nothing seems to resolve the issue. I'm looking for ideas on how to disable CSM while still being able to access UEFI to enable Secure Boot.

It sounds like a tricky situation! First off, make sure you’re either initializing the TPM keys manually or verifying if the BIOS isn't setting them to some default that might be blocking the boot. Also, try pulling out any unnecessary SATA or USB devices while you're at it—sometimes, hardware conflicts can lead to boot issues. Have you tested booting using the integrated graphics HDMI? That’s worth a shot too!
You might need to have the TPM module installed when you do a fresh Windows install for Secure Boot to recognize it properly. If it's not detecting the TPM keys correctly, it could lead to these boot problems. But since you can’t even get to the Secure Boot options after disabling CSM, it complicates things. It might be worth testing again with just the essentials connected and seeing if that helps.
