Is it possible to downgrade to the first release of One UI 8?

Wait 5 sec.

Hi, I have a Galaxy Watch 4 SM-R860. When the first release of One UI 8 came out, my watch worked fine and the battery was really good. All sensors were working well.But with the second patch (which was supposed to fix some issues), my watch got worse battery life and now it can’t last without power saving mode on.So my question is: is there any way to downgrade to the first release of One UI 8?Thanks! And sorry for my English.
