Induction for vbac due to big baby?

So I am now 37 weeks and baby is measuring over 8lb with a very very large head (my first had a very large head and never engaged party due to it). He is expected to be nearly 10lb by 40 weeks.

I'm worried the bigger he gets the less like a vbac will be.

Would you ask for an induction at 40 weeks to limit his size and try for vbac or go overdue by 12 days (drs preference) and attempt to birth a nearly 11lb baby via vbac? I'm mostly worried about his head size too as it was an issue for my first and thus time his head is even bigger.

I'm worried if I go over my vbac will turn into another c-section due to his size.

What would be your preference? Any advice welcome.
