Rear Derailleur to run 34t cassette (10 speed)

I currently have a sram red set up with 50/34 chain set and 11-28 cassette (10 speed).
I want to run a bigger cassette - 34t (don’t judge, I have my reasons!).
Any advice on which rear derailleur would be compatible? Most road/gravel derailleurs I’m seeing that take 34t are 11 speed. I’m not sure if mtb options would work. Any suggestions? Thanks.

Was going to mention SRAM Apex or Wifli mechs but they are 32T. What about X9 or GX 10 speed

Thanks for the replies, I’ve gone with the Apex and 32t cassette. There’s issues with the pull ratios between the shifters and the mtb mechs.
I’ll have to focus on dropping more than a few kg between now and August, the Zoncolan after 100 miles of day 8 in the Alps/Dolomites might need an ebike never mind at 34t cassette:cry:
