Do Arria A10 LVDS inputs support weak pull ups/downs?

Does the Arria A10 support internal weak pull-ups/pull-downs on the LVDS input lines? I can't find this info in the datasheet?

Hi,

Check for “Internal Weak Pull-Up and Weak Pull-Down Resistor” in following datasheet & Quartus tool has internal weak pull-up & LVDS options but it allows either weak Pull-up or LVDS not both simultaneously,check below snap.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
