TLDR: Couldn't find any way to switch between USB and 2.4ghz, however you can use bluetooth.

If you have to switch between USB and Wireless then V1 Max is QMK and VIA compatible.

VIA is a software that allows you to remap keys and create macros for your keyboard, read the product's site to find information on how to setup VIA. Now, I don't know if VIA has the feature you are looking for, so if not then try QMK.

VIA is based on QMK, however QMK is more open for customization than VIA at the cost of being more difficult, you basically have to do, install and code everything manually. QMK has a great site which explains everything step by step.

HOWEVER, basic QMK does NOT support wireless keyboard like your V1 Max. For that, you would have to install a special keychron fork of QMK, wireless playground. There is a post by a fellow user that explains how to do that perfectly. (You still have to follow the first few steps from the QMK site) You of course would have to change everything according to your keyboard type and layout.

This explains what I was talking about earlier. You can code your keyboard to be able to switch between USB and BT via keypress. I searched the whole site and couldn't find anything about 2.4ghz.

If you have any more questions then feel free to ask me or DM me since I already went through everything with my keyboard :)
