This whole check is a bit of a mess we should think a bit more. It could also be a non-constant slice (see if not)

@ricardoV94 by this line it could also be a non-constant slice do you mean to say that dynamic slices (non-constant slice) are also need to be skipped?

Also what is your view if we check for tensor variable and only in that case graph node get modified? (solution for mess)

[ricardoV94]

I think this check should be just something like

if any(
            (
                    isinstance(indices, TensorVariable)
                    and indices.dtype.startswith("int")
                    and any(not b for b in indices.type.broadcastable)
                )
            )
            for indices in mixing_indices
        ):

Basically rulling out potentially repeated integer indices.
