These boards support CAN transciever? For example sn65hvd230.
I know that they have a few number of GPIO but maybe someone has connected CAN transciever? (TX, RX, 3.3V, GND)

Yes. ESP32 supports CAN and these are featured S3 boards.

@teastain2 Thank. Is the amount of GPIOs enough? There are few free

@luki743 LilyGO T-Display S3, easy;
T-Embed not so much.
The T-Embed repository is here:

You only need one GPIO and gnd if the sn65hvd230 is powered by the other device.
CAN takes a single digital output (GPIO) from the ESP and converts it to "differential" + signal, - signal.
The "Grove" connector maybe configured as CAN and maybe a few spare GPIO on that unpopulated development pad on the lower left of the image.
