[SCIP] Running SCIP with branching disabled

Dear SCIP community,
can you tell me if it is possible to run SCIP in such a way, when only cuts (at root node) will be used and no branching?
We use SCIP in "a console mode" as a standalone application.

My question is triggered by an effect my colleague found: one of commercial solvers solves some of Integer Linear Programming problems much faster by cuts only, without any branching. It was a kind of Constrained Programming problem, to find a feasible solution of a system of linear equations with binary variables.
"Only cuts" took a few seconds and "cuts and branching" - a few minutes.

Regards,
Sergey
