I'm assuming your mimicking the behaviour of radiobuttons with an nanoflow to check one boolean and uncheck all other booleans?
If it's just the styling then maybe this Codepen demo can be of some use?
Some other cool options for inspiration: https://freefrontend.com/css-checkboxes/
I would suggest using an enumeration instead of booleans. The only downside is that the input boxes will be below all the options
