The problem with this is that the Belgian rebels are militarily strong enough to hold off the Dutch, even without overt French support. Eventually they will prevail, even if they are initially defeated.
They were getting their asses kicked all the way to Brussels. In ten days, they had lost control over the northern half of present-day Belgium and Dutch troops were closing in on Brussels. And that for a campaign that was only meant as a show of force. (For which it worked, Belgium was originally supposed to contain more of the Dutch catholic areas, but after this weak showing it was reduced in size.)
The French were requested by one of the Belgian leaders who was officially not supposed to have the authority to do this. So there's our POD.
Alternatively have one of the local houses unite the Netherlands, like the duke of Brabant, Limburg & Lothier, the duke of Gelre (Guelders) & count of Zutphen, the count of Flanders, the count of Holland & Zeeland, the duke of Luxembourg etc.
To achieve this a more succesful marriage between Willem IV of Holland and Joan of Brabant is an option. A surviving dynasty based on control over Holland, Zeeland, Hainaut and Brabant would lock out the Valois-Burgundians. With a solid and uninterrupted control over the entire spine of the Low Countries, that's a base to build on.
OTL their only son died young and Willem lost his live at the Battle of Warns (battling the Frisians as several of his predecessors) in 1345, leaving Brabant to be eventually scooped up by the Valois. With a few butterflies, you can start a more indiginous Dutch dynasty.
As an aside, without the Burgundians the term 'Low Countries' might not appear, as they were termed such in contrast with the higher situated Duchy and County of Burgundy.
