Other Configuration Manager-related features and issues
Sorry, it's unclear exactly what you are asking for here. There is no such thing as a branch distribution point in ConfigMgr. I'm assuming you just mean a DP hosted on a Win 10 system. If so, if there any reason you don't use the built-in scheduling and throttling mechanism for distribution points?
Technically you could certainly enable LEDBaT for this traffic, however, it could impact other connections which may be undesirable. Additionally, since there already is a relatively robust mechanism built-in, I'm not sure why'd go down this route.
As for Win 10, that's irrelevant here as LEDBaT is a sender side technology -- the receiver plays no part in LEDBaT other than receiving the packets as normal as they are delivered and is completely unaware of LEDBaT.
