Nooooo.... not really.
Sure, Germans wanted to surrender in their West and keep fighting Soviets in the East.
I can think of at least twice when they offered that deal to Western Allies.
And for sure, Stalin was paranoid and willing to believe anything suspicious, so he accused his allies of whatever he feared.
However, I've never seen evidence that any western leader seriously considered German offers for "western only" surrenders.
Now, if you wish to discuss Operation Unthinkable, we can, but that was planned after German surrender, not before.
