Validate fields in Redux framework

I want to validate the input fields in theme option of redux framewwork.
I try to follow this instructions:
https://docs.reduxframework.com/core/the-basics/validation/
It ‘s OK but it only validate ONE value like ‘not_empty’ or ‘numeric’.
So can I make validate both ‘not_empty’ and ‘numeric’ value?
If possible, let me know how to solve this problem.
Thanks!
