Breakpoints for visibility stacks / vertical

What would be the best way to separate two different breakpoints for mobile?
I would like to have separate breakpoint for iPhone SE and the rest of the phones for the header. Squeezing font size for smallest screen makes header too small for other sizes.

edit: Using Column stack inside visibility for custom breakpoints?

Foundry does not have custom breakpoints. They are preset purposefully within the framework so that they match throughout all of the different stacks.
