Question

How do you say this another way?

That's not how I roll.

Answer

I would never say your suggestion, though others might. It’s a little vague and folksy for me.

Depending on the context, more mainstream are:
That’s not how I do things.
That’s not my way of doing things.
That’s not my practice. (In speech you can emphasize the ‘my’ to contrast it with another way already mentioned.)
That’s not something I would (ever) do.

Answer

That's not how I handle things.

Answer

You can say, that's not my style.
