It's unfortunate that you are so worried about this invasive exotic.
Nothing, Absolutely Nothing inhibits Chinese wisteria once it gets started.
Extremely fast grower, and when it starts sending out adventitious vines from the root zone across the lawn, they send roots down too far to dig back out... and regenerate every time that you try.
While an interesting specimen if it was possible to keep tree form... requiring constant near weekly pruning... tends to require far more effort than most of us are willing or able to provide...
And worse, most of those mail order plants are seed grown and will not bloom for a very long time (decades).
I once worked on a garden with one of those that never bloomed in the 15 years or so that I was there, and It was 10 years old when I got there.
I brought a vine that I rooted from next door... it bloomed in season as well as producing off-season bloom...
I used to have pictures of entire wooded lots covered in wisteria... Once this invasive escapes, there's not much that can be done... incredibly aggressive, far worse than kudzu in my personal experience.
