I can't see a show stopper here for 4.20.
But I would avoid upgrading both Xen and the dom0 OS at the same time.
So I would first go with Xen 4.18, which should work with netbsd-9
(maybe you'll have to upgrade the dom0 kernel to the latest 9-stable).

Then, if all is well I would upgrade the dom0 to netbsd-10, and then Xen
to 4.20

It's been a long time since I used pygrub; I think it has been deprecated
by Xen. But you can just copy the kernel to the dom0
