Sheet Permissions from Template

Can someone check my logic here?

I have locked rows in my timeline templates that have formulas in them (VLOOKUP for a project summary at the top) that I need my PMs to not edit. Currently, they have admin permissions and can delete the formulas. It was suggested to me to make them editors in the workspace, but they'll still be sheet owners who can override my locked rows.

Am I right in thinking that making them editors won't help my problem?
