Can't customise folders in Tahoe

Can you say more about this? Do you mean the (•••) symbol that usually accesses more options, and if so, where are you seeing that button that you are hoping will lead to Customize Folder?

Like others, I do see the Customize Folder option with a secondary click (control-click, two finger click) on a folder on Tahoe, right below the row of Tag colors:

Note that you can only Customize actual folders, folder aliases cannot be customized:

Also note that certain folders cannot be customized, like the ones at the top level of your internal drive (Library, Uses) and some app-created folders like the OneDrive folder.
