Dynamic type based on another value

Given a theoretical example like this:

const formDef = type({
    agree: 'boolean',
    clauses: ['===', 'first', 'second'],
})

const formDef = type({
    agree: 'boolean',
    clauses: ['===', 'first', 'second'],
})

Is it possible to only have

clauses

clauses

be required if

agree

agree

true
