I have a new in box MacBook Air M1 2020 A2337 in my shop where the battery will not charge, Apple says it needs a new battery. Visual inspection shows no puffing or other irregularities on the battery. Is there a possibility to trick or bypass the BMS into trickle-charging the battery back to operational status without removing the speakers and battery?
Is this a good question?

It's a pretty easy for the USB-C ports on these models to get damaged. If the battery looks good I'd recommend removing the USB-C board and inspecting the pins on each port for signs of damage. You can see how to do that here.

I alway use. A USB-C power meter to measure the current load. Often I encountered power controller chip issues in the Intel systems. Here it’s a Texas Instruments CD3217B12 – USB and power delivery IC that could be the issue. Measuring the power at the USB-C port.
I'm in the same boat here, brother. I work at a school, and we had four (4) of these A2337 MacBook Air M1 2020s in storage, never touched, never used. Pulled them out to deploy and they are showing "battery needs service". I was able to buy a battery and try to swap it out to see if that's the issue, but I'm intrigued to see if it's the USB-C ports.

Update: I ordered the USB-C port replacement and got it swapped out. Unfortunately, that didn't fix the issue. Looks like it's truly the batteries on these, which sucks because we currently have five (5) MBAs with bad batteries.
@lesit - When storing a system you want the battery to be around 50% charge and make sure you've fully shut down the system (not Sleep mode) even still sitting over a year not being used is iffy!
Using a second working Mac I would try using Apple Configurator to see if that fixes things. Reference this on using it How to revive or restore Mac firmware When the battery is fully discharged the EFI settings get lost which is why you need to run it.
