Or "--ignore-other-worktrees" for "git switch". This leaves things in a weird state though, as modifying the branch from one of the worktrees will effectively change the ref the other is pointing to, but won't update the other's working tree, making it look like it's preparing to revert all the changes that the first worktree made. (obligatory mention of jj, whose workspaces track what state they were snapshotted at, thus never losing what the true diff of a workspace should be, allowing a "jj workspace update-stale" to safely update the working copy with whatever the other workspaces changed (if you change the working copy and in parallel from another workspace change what that workspace points to, you'll get a saved commit of the working copy changes before being updated, which you'll need to squash/rebase wherever those changes were needed))
