Hi, @EdsonSV
Yes, you can do that.
The W11 product key works on W10 and visa versa.
You can clean install W10 with the Microsoft media creation tool.
Download Windows 10 (microsoft.com)
There is no official guidance from Microsoft on this.

You should be able to.

In any event if that doesn't work you can clean install W10.
There should be an option to select a W11 or W10 recovery after you launch the media.
