New ContributorWarning (13028): Removed fan-out from the always-disabled I/O buffer....
So what is the issue and your goal at this point? You have disabled tri-state buffers that are not being used in the design.
Also, it should be mentioned that there is no tri-state logic internal to the FPGA fabric, only in the I/O cells, so that may be part of the issue here as well. Note "I/O buffer" in the warning.
If you are trying to determine what resources are being used and what has been removed, use the Technology Map Viewer (Post-fitting) to see a schematic of the used device resources post-fit.
