[Closed] SRAM rival 1 shifter question

Hi,

I’ve got a drop bar gravel bike with rival 1 11 speed on it. I want to change it to flat bar.

I see sram do an apex flat bar shifter bit it’s quite hard to get gold of- mostly only German places have it and even zero are out of stock.

Question is, as it’s a sram mech on a sram 11 speed cassette, can I use any sram 11 speed shifter? I can’t see why not.

Thanks
