Yup.
I already unlinked my main credit card and replaced it with a virtual one with $500 limit, just in case. If you go to the upgrade menu, FSD is checked by default.. if it functions just like the website where all it took to buy the boost upgrade was just one click ( no checkout. no confirmation, no breakdown of costs. Basically amazon 1click purchase) , you are one tap away from spending a non refunsable $7K + tax...
