Conditionally Prevent Record Edit?

I know I can disable form inputs one-by-one via

->disabled(...)

->disabled(...)

. But, what if I wish to prevent editing for entire page based on a field in the model. Like if

$record->is_locked == true

$record->is_locked == true

?

If would be great to prevent the edit page from opening or in the least open to a view page.

Thanks in advance for any guidance!
