Chargepoint Home Flex can do it.

That's a lot of extra expense going from 48 to 50 amp output (11.5-12.0 kW). You would have to upsize from 60 amp circuit to a 70A/80A amp circuit for minimal improvement.

Plus with a Lightning Standard Range battery it is limited to 48 amps anyway.

I would dial it in at 48 amps and wire accordingly

One thing the electrical inspector who came to my house told me was that for EV chargers where the max current is set by software in an app, he requires the wiring to support the max current the device can be set to since it could easily get set to that higher setting.
For those chargers where the setting is a dip switch or jumpers inside the unit, he allows the wiring and breaker to correspond to the setting its on. But he checks the setting as well.
I was actually kind of impressed how knowledgeable the guy was about EV charging.

I set my Ford HPWC to 80 amps for my ER truck. Runs through 100 amps breaker from the panel. No problems.

He‘s correct. There are many inspectors that don’t know this.

Hello

I got my new charger ready to be installed and the lightning pro with regular battery may arrive next week.
If I set up the charger to 50 amps can the battery handle 12kw? Or should I keep it at 48 amps?

240 volt x 48 amp = 11.5 KW which is slightly more than the BC can accept (11.3 KW). The output is 10.5 KW. You should be using a 60 amp breaker to be in code with the 80% rule. Any higher setting than 48 amps won't increase the charge rate assuming fords data sheets are correct.

Are you saying that my 80 amp setting on a 100 amp breaker actually only maxes at 48 amps.

Not if you have a 22 or 23 ER. They have dual onboard chargers you can use the whole 80amps theoretically. If you have 2024 they all max out at 48 amps, with the exception of some Pro ER's for businesses.
