I did it since Redmi Note 5 pro and my Redmi Note 5 have the same CPU = SDM636.
I installed e-0.21-q-20220125158536-dev-whyred.zip and everything is OK !
So my Redmi Note 5 is under /e/OS and it’s good !!!
Great news! Now that you found it worked, you could try to install Download 1.85 (APK) | AIDA64 to see if your devicecode is indeed whyred. Your note of the device code for Redmi Note 5 might be useful for others!
