Will it be possible to use model 318 for EFG, SPG, SPH formulations ?

Previously, when using the polymod library, it was possible to use the following parameters:
ODE solver id (ODE)
Jacobian calculation method (JAC)
Varying these parameters often helped solve the tasks.
in the latest version LS-DYNA (318 model), these parameters are not available.
Will they be available in future versions of this model?
If these parameters are not available, it would be useful to understand:
1. Why did they become unavailable to users?
2. What values ​​of these parameters does the program use "by default"? -

here is another example where the problem is solved using "old" external models from the library PolyUMod and an old version of ls-dyna.

the same model is not solved in the new version of ls-dyna, where the built-in material model 318 is used
