I could not find anything aarch64 for that device, all I found was 32 bits.
That said, it seems to have mainline uboot and kernel support 
(zynq-zc706.dts), so it could be installed using the steps here 
Since we usually don't build uboot for that device, I made a version for 
you to test, and left it here https://people.centos.org/pgreco/zynq-zc706/
The normal images provided by CentOS use kernel 4.14, but if you need an 
image with a newer version, we have this test image here 
which uses 4.19

Please let us know how it went.
