Yes. It certainly won't be the majority view, but I think he would. If he'd wanted all of Poland, the M-R Pact wouldn't have given half of it to the USSR. There would be something of a standoff in the East, since Hitler does want Ukraine and the Caucasus, but isn't really ready for war. He won't really have a pretext for Barbarossa unless a war is already underway; he may attempt to do so on his own timetable, but he may delay things long enough that they actually don't happen. Unlike most, I don't think Hitler was so committed to his long-term ideological goals that he was willing to risk everything, at any cost, to get Lebensraum. I think he sincerely thought he could bluff the West over Poland again, and I think he was disappointed when war was declared.
This applies only to Hitler's ambitions, not with events beyond his control. Stalin may have something to say about the new western border, and a preemptive war by either the USSR or Germany is entirely possible, though I don't think Hitler wants it before June 1941. Another possibility is that Chamberlain's government falls, and the new one declares war. The Nazis are still going to commit the same atrocities in Poland that they did IOTL, if not more, so that may cause war. The likelihood of Hitler actually getting away with keeping his half of Poland until his natural death is practically zero. But I do think his ambitions ended there -- it's just that they were already too far-reaching for peace.
