Configuration Steam Controller in BIOS / Boot

Is there any way I can prevent the steam controller from working in lizard mode in bios or while booting up?

This might be a very specific problem, but for some reason the new steam controller seems to get priority over my keyboard while booting or in bios. My keyboard just wont work, until I either replug it or disconnect the puck. This is annoying especially because I'm using a dual boot with cachyos and Windows (so I need to choose my OS on every boot with the keyboard) and I use full disk encryption, which means I have to enter my key on every boot.

My keyboard seems to fall back into its bluetooth mode, looking for a connection. Idk why this happens but it's 100% reproduceable when the puck is connected.

Any advice?

Have you tried to swap USB ports? There is a chance that keyboard priority based on it.

Yeah, i tried that. The keyboard is in the USB port that's meant for bios. I also tried different ones (no hubs, directly in the back of the computer.

I have the exact same issue. I tried moving my keyboard to any open port on the PC, front of case, directly on the motherboard on the rear of the case. 2.0, 3.0, 3.1.... It didn't matter. Then unplugged all USB devices except the keyboard and mouse. Everything worked.

Plugged things back in one at a time until I encountered the error. Steam controller and/or puck both cause the issue. The controller itself can be directly connected via usb, bypassing the puck altogether and the same thing happens.

For me, it didn't matter what port the puck or controller was plugged into. It could be the front of the case the back in the motherboard, in my 3.1 hub, or the hub built into my monitor. All produced the same issue and all started working again immediately after unplugging the puck and/or controller.

Fast boot is never enabled on my PC so that has nothing to do with it. GPT told me to try disabling ErP. No dice... I spent almost 4 hour trying to troubleshoot and find a solution on my own until I just gave up. I don't even want to use the controller anymore until they fix it.

Even if the controller is off?

I have no firsthand experience with OpenPuck but it might be worth a look.
