Downgrade to 11.2.3

[nmeed]

Can anyone please tell me if it's possible to downgrade to 11.2.3 without having to wipe everything first? I haven't seen anything about downgrading to an earlier version of Big Sur, just to Catalina. The font change and all the animation bugs, especially in Safari, are really bugging me.

Edit:

Thought I could just download and install it. Ah.... not recommended. Going back to 11.3, hope it fixes all these popup errors lol. AH I see what the issue is. Safari doesn't get downgraded, hence the issues...

If you install 11.2.3 on another disk (external) during the last stage you can transfer information from another Mac. Select the 11.3 drive.
