looking for a (very specific) Keyboard

ok so I'm looking to upgrade off of this 60% keyboard because i need my F Keys back. I'm genuinely going insane because i haven't found the ideal one.

so I'm looking for:

• TKL or bigger
• white
• ISO layout (ideally ISO-Swiss)
• 2.4GHz or USB C that i can replace
• SignalRGB compatible (if possible)
• hope not to go over like 250CHF but i will if money allows it.

I don't really play a lot of fps or rhythm games so latency is not a huge factor
