Making all fields in a Schema optional while keeping access to `.fields`

Is there a way to make all fields on a

const s = Schema.Struct()

const s = Schema.Struct()

optional, while still being able to access

s.fields

s.fields

? Using

Schema.partial(s)

Schema.partial(s)

makes

.fields

.fields

unavailable
