As far as I know, there is no any such terminology called ‘constraint guard’ in LRM.

From the 1800-2017 IEEE SV LRM
18.5.13 Constraint guards
Constraint guards are predicate expressions that function as guards against the creation of constraints and
not as logical relations to be satisfied by the solver. These predicate expressions are evaluated before the
constraints are solved and are characterized by involving only the following items:
— Constants
— State variables
— Object handle comparisons (comparisons between two handles or a handle and the constant null)
