The bottom line is that freedom (of any description) and determinism are incompatible. And no amount of word garbage from the compatibalist flavour of determinism (quoting Kant) can change this.
If you want to contest that use of language (which is all it is), fine.
However, it doesn't change the fact that having
the ability to do what we want, is compatible with determinism because it's what we want that is being determined.
Neither does it change the logic that, to the extent something isn't deterministic, it is random. So unless you think randomness gives us 'freedom', you are saying that 'freedom' can't exist.
The only way for any form of freedom to exist is for it to be derived from a source which is not constrained by the scientifically defined rules of physical reaction to previous events.
Once again running away from the logic: if all the considerations that go into making a choice, do not fully define that choice, then any remaining choice must be for no reason, which means random.
Being "derived from a source which is not constrained by the scientifically defined rules of physical reaction to previous events" doesn't change that logic one iota.
Are you going to have the honesty and courage to face that?
