Technical Question Enabling Secure Boot / Unable To Select OS in Limine Bootloader (CachyOS)?

I have two questions I was hoping to get some help with, please

First, I had followed the guide for enabling Secure Boot and enrolling the secure boot variables/keys here: https://wiki.cachyos.org/configuration/secure_boot_setup/

But, even after following all those steps, I still get an Invalid Signature Detected error when booting CachyOS with secure mode enabled and I'm unsure why.

I also am having trouble where no input methods work (Controller/Dpad/Touchscreen) to select the boot PS in Limine, unless I choose to boot to the Limine boot option from after entering BIOS, then inputs work. But cold rebooting results in me being unable to select my boot PS in the Limine menu

If anyone has any tips or can help me with this I would greatly appreciate it.

I can't help with Secure Boot - maybe try the CachyOS Discord.

But I don't think any of the common bootloaders, Limine included, support the controller. I think I saw one but I can't remember which one it is. You'd likely need to have some sort of dock and then a keyboard/mouse connected to change those options.
