The reason you can't find it is that i do not believe it is possible to have that level of controls over mobile data.
You can change your connection settings to turn off 5G, and you can turn off background data for each app in their own settings.
You can also use connection settings- data usage - data connection for apps. This will list your apps and select WiFi and mobile data connections or not.
But I do not believe you can tell any specific apps to 'only use 5g' or only 4g. It is either allowed to use WiFi or mobile data.
