.... huh, I'm not sure that I understand the question... If you ask to connect pull-up resistors to 3.3V GPIO pin, then the answer is: yes, you can.

These diagrams are not very readable - even when elements labels are present, the observer has to take a look into some elements (eg. transistor) datasheet for pinouts to get the complete picture... I preffer "normal" schematics of the circuits instead.
Anyway, your chances to get reliable answers is dramatically increased when you attach schematics to your questions....
