Welcome to the forums @Yasir.

Using firmware over 4-years-old for a router today isn't recommended.

Even the stock Asus firmware for the RT-AC66U is much more current (2021).

Are you connecting with the 2.4GHz band to the main router? If you are, it may be possible to use another 5GHz channel to re-broadcast with (even if I don't think it's possible with Asus' routers, from what I know).

If you're using the 5GHz band for the backhaul, it can't be any other channel than what the main router is broadcasting.

If you want to use a different channel, you must make the change on the main router and then extend that via the repeater. Either way, both the main and the repeater will be on the same channel in the end (it can't work any other way).
