No. The best you can do is set the IO pins to be open drain and then use a pull-up to 5V
Not all the pins are 5V tolerant, Only pins with a type of FT and FTf in table 13 of the datasheet can take 5V.
If you need sharper edges than a pullup will give you then you need to use a 5V output buffer to drive the lines.
