Once you install the new firmware - is it possible to go back?

As far as I know, there is no way to go back.

You can infact go back. Download the previous firmware from Canon's site and then use the EOS Utility to revert. Did it yesterday going back to 1.4.0 on my R6. It was super duper easy. Once you camera is connected to the EOS Utility click on "Settings" then "Firmware Update" and follow the prompts. It will say that you have the latest firmware but just click on "next" and it will eventually take you to a screen where you can select the firmware from your computer. You select the old firmware and then it shows you on your camera screen that you are reverting to a previous version. See below for screen shots of the process.

Thanks for sharing, I tried this , but it only says "failed to transfer firmware" and it doesn't do anything else.

I upgraded two R5s and no issues so far. In fact, it *SEEMS* like eye AF was much improved for me. I had a shoot the day after upgrade and I tested after upgrade with no issues at all. Shoot went perfectly and definitely seemed like eye AF performance and accuracy was improved, idk, maybe it's just placebo, but I had 2 shoots in a row with 1.4.0 where I felt like eye AF was letting me down so I switched it off.
