I didn't seen support for R6900 but I did see support for model numbers that are near to R6900, such as the R6800:
Should I just use the procedure for R6800?
Thanks In Advance.

No. A similarity in the model number does not indicate that the hardware is similar - in fact, Netgear and other vendors are known to completely change hardware even between revisions of the same device.
A quick check on wikidevi for your R6900 reveals that v1 is Broadcom-based, while v2 is Mediatek-based. The v2 is probably easier to support.
NB: Never try to flash a firmware for a different device if you don't have at least serial console attached to be able to recover your device. Depending on the device, there might not even be a recovery mode.
