How to get best out of RTX3080Ti i9-12900H with an external monitor.

I recently bought ASUS VG27AQ3A 27 HDR GAMING 2K FAST IPS FREESYNC, G-SYNC 2560x1440 1MS 180HZ DP HDMI MM ELMB SYNC,%130 Srgb Monitör.. I also bought Adauxter 10k 8k HDMI 2.1 cable. I can only get 2560x1440 native 144Hz and monitor is not giving me over 60Hz in those resolutions

The monitor capable over up to 180hz over thunderbolt. SO the question is, can I get the most with mini thunderbolt to thunderbolt for the combination? Or should I return the monitor and get something more specific? Thanks for the help guys.
