Android Question Is it possible to ignore keyboard spell checking

Is it possible to prevent the keyboard from performing a spellcheck.

For example, i am using Gboard and entering information into a textfield. This field is a username on a Login page and the keyboard is telling me that it is spelt incorrectly (underlined with a red line)

When I tap on the field again the "Add to Dictionary" pops up.

I don't want any of this behaviour.

Thanks
