The garuda isos as it stands are all made with desktop in mind. However there are a lot of users who use it on their laptops. And a lot of garuda's features need to be disabled/removed for it to become usable on laptop.
So my suggestion is that instead of shipping the iso with a custom kernel like
gamemode you ship only the default linux kernel and lts counterpart with no tweaks of any sort. After install let the user configure their install with Garuda Setup Assistant. A desktop user can get all the performance tweaks and custom kernels. Laptop users can configure the system for their laptops.
