No, there have been mixed results doing this and the schematic is not clear. There are stories of damage trying this.
Yes, it is intended to output 5V to power some sensors but putting 5V into it may back feed and cause a failure.
You can put 5V into the two prong battery input, though.

Thank you for your quick reply!

I don't want to power the lilygo t-display-S3 from the USB-C connector. Can I use the 5V pin or is it an output?

@teastain2
Thanks for the reply, I will try it !

In the case of T-Display-s3, the antenna just needs to be plugged into the connector and the Bluetooth/Wifi already works through it, or does something have to be soldered through it? Thank you!
