If you do not use the QPLL in your design, connect MGTVCCAUX to a 1.8V supply. Because the QPLL will not be used, this 1.8V supply does not need any special filtering for MGTVCCAUX.
A good candidate to supply this voltage is the VCCAUX voltage power supply. The unused QPLL will be in a powered down state and will draw less than 50 uA.
