Well I have no statement from Gigabyte about this but as far as my experiments go that is true. Actually in the supported hardware list the RTX6000 is listed explicitly with the term "passive" which agrees with my findings.
You should be able to use blower fan GPUs in the rear canister positions as the airflow is in the correct direction there.
But please keep in mind that using GPU fans may result in a situation that the Chassis fans could be "driving" the GPU fans. I don't know the design of the GPU fan PWM driver but it might become unhappy when the GPU fan starts to generate energy in stead of consuming energy.
In short: remove GPU fans and caps (but do keep the heatsinks ;-P ) or buy passive cards.
