New ContributorWeak Pull Up Setting
When compiling a Cyclone10 LP device, unused pins are set to “As input tri-stated with weak pull-up”.
Looking at the compiled report, the display is different only for unused VREFB pins.
Is Weak Pull Up enabled for this pin?

You can refer to .pin file on the connection for the unused pins. The .pin file will be generated after completion of the Fitter compilation.
You can also refer to link below:

What view is this in Quartus tools?
As far as I understand, you could set the unused pin as shown here:
whereas the Weak Pull-Up Resistor shall be set through pin planner or assignment editor:
Both are different setting.
Thanks.
