[SCIP] Deactive constraint in a substree

Dear all,
   As I defined a branch rule on a binary variable of which a constraint
becomes feasible in in the upbranch, can I declare this constraint to be
inactive at the branch node?
    For example, constraint: sum_{i=1}^{n} x_i  / n <= y,  x_i \in {0,1}, y
in {0,1}, when I branch on y, and in the branch y =1, this constraint is
useless,

Best regards,
XU Liding
