Hi, I'm trying to install macOS Sequoia on my HP Elitedesk 800 g4 35w DM, and I am able to boot into recovery and run the installer, but at about 40 minutes ish, it reboots itself each time. I've already set SecureBootModel to Disabled, as well as set DisableSecurityPolicy to True. I'm also using a USB 2.0 and I've reset the NVRAM many times. Please help! Here's the efi and specs.
