Unlikely unfortunately, they don’t currently offer replacement motherboards at all.
When the ifixit repair parts initially leaked, they had a replacement motherboard available but priced at $350. Later when ifixit officially started ordering repair parts, the motherboard was no longer available.
My guess is that it wasn’t worth selling the motherboard for $350 when a 64gb deck was only $400. I’d imagine the same issue would apply to an “upgrade” motherboard.
