Option to protect all sheets in a Google Sheets spreadsheet?

Underneath “Tools” in the menu bar, there is the “Protect Sheet” option, which pops this sidebar on the right-hand side of the screen:

Protected sheets & ranges

Which works well, however there doesn’t seem to be an option to protect all sheets in the spreadsheet.

After googling this, I found only one relevant thread:

Protect All Sheets by Default

Which is just a collection of complaints of various users who want the same feature.

Is there an option to protect all sheets in a Google Sheets spreadsheet?
