Setting tolerances in JuMP - is there an Optimizer-independent way?

I’m tired of multiplying my objective functions by large numbers

Why are you doing this?

Is there a simple Optimizer-independent way to set tolerances in JuMP?

Nothing that is widely supported. Gurobi and CPLEX support setting MOI.AbsoluteGapTolerance() and MOI.RelativeGapTolerance().
