I bought an EL sheet and driver, but when I power them, the driver beeps
It's logical because the driver is AC, I guess

But is there any way to silence the beep, or are there silent drivers out there?

The noise is probably coming from the voltage boost transformer.  Some part is vibrating.  You may be able to reduce or stop the vibration by potting the circuit in plastic resin.

The driver is a plastic case with the top face open, which is filled with resin
So how come it's still vibrating?

Must be a really cheap transformer. :(
