How to force a Note 9 to always use 5ghz on BT smart hub 2

How to force a Note 9 to always use 5ghz on BT smart hub 2. I can't bar the 2.4 ghz option on the hub as some of my devices will not operate on 5ghz, neither can I split the SSID between the 2.4 and the 5 as you can't do this on the new 'not so smart'  BT smart hub 2. Is there a way to force my note 9 to always choose 5ghz, please don't suggest I go to the 3 dots on the wifi screen and select 5 as it isn't available on my note 9. Thanks in advance for useful suggestions.

buy an extender and thats how I did what you want

Tried that already, didn't help.

on my extender I was able to separate the 2.4 and 5g so only I attach to the 5g

Ok I see where you're coming from, my extender disc doesn't have that option. I'm looking for a fix to make the phone keep the connection to 5ghz channel instead it switches to the 2.4 after a few minutes, dropping from  140+ Mbps to as low or lower than 3 Mbps. Sorry if I didn't make that clear in my original post. Thanks for taking the time to respond.
