1) Is there any power down sequencing concerns with the Ultrascale XCKU060 FPGA?
2) Is there any backwards biasing concerns that might damage the part?

1) power down sequence, just turn off . e.g. if the mains disappeared, the chips have to survive.
2) chips are not designed to be back powered, it heats up the IOB's, to much heat kills or at best shortens the life of the chip.
data sheets have references on limits
The bottom line is about heat.
power up / down, what the designers dont want is some supplies on, other off for long periods.
