type MyType() =

    member _.MyMethod(?beep: int, ?bap: int, ?boop: int) = ()

    member this.Foo = this.MyMethod(bap = 3, boop = 4)

Since parameters can be optional not all of them need to be present and they can be out of order. Also, if I'm already specifying them explicitly there's no need to also show hints.

Also in the method definition, hints are shown even when types are specified which is questionable.
