The bank is a private business and can lend, or refuse
to lend, money based on any criteria it chooses.
They can also reap the rewards, or otherwise, of those
policies.
Anyway if EV's were any good, and were competitive with
real automobiles, then they wouldn't need taxpayers' subsidies, they
wouldn't need taxpayers' funds for chargers, and they wouldn't
need banks and governments to try to force you to buy one.
If an EV cannot do the job you are buying a vehicle to do
why would you buy one, at any price?
