Is it possible to restrict simulink from changing my solver setting to fixedpoint ?

Is it possible to restrict simulink from changing my solver setting to fixedpoint.

I have a model with no continuous block but have set the solver as ODE1, when simulating simulink will change it to fixed point and will give warning.

I can disable the warning by setting "SolverPrmCheckMsg" to none.

But can i restrict solver changing ??
