The current answer is No, but the situation may change in coming months.
PGWP was never meant to be extended, but in 2022 and 2023, Canada allowed this to happen.
In 2023, the folks was benefited from the 2022 extension was eligible again as long as their first PGWP expired after September 20, 2021.
If your PGWP expires after December 31, 2023, there's currently no way to extend; and I don't know if IRCC is planning something similar or not.
Hopefully by now you have 1+ years of experience in Canada, so I highly suggest looking into PR options (if you intended to live here) or get another type of work permit.
