How to use discrete amd gpu in bottles (or globally)

After about a month of using Nixos, I realized my apps don't use my discrete gpu. I have an intel cpu with integrated graphics and a discrete amd gpu. On windows I had set all apps to use discrete gpu when the laptop was on power. Before I say more, some info for my system:

My main issue is that my bottles apps (bottles is a wine prefix manager) can't run its wine prefixes with a discrete gpu. I have the nixpkgs version of bottles (not the flatpak one which the developer suggests using). Things I've tried:

• Enabling/Disabling the "use discrete graphics" option inside the bottle (only the integrated gpu is being used)
• Launching bottles from command line with DRI_PRIME=1 and bottles opened for a little and then closed, by reporting this: ::: spoiler terminal output

:::

• Launching the game from command line with DRI_PRIME=1 bottles-cli run -p OuterWilds -b Outer_Wilds after having enabled/disabled the "use discrete graphics" option inside the bottle (kept using the integrated graphics instead)
• Launching the game from bottles gui, after using the enviroment variable DRI_PRIME=1 and enabling/disabling the "use discrete gpu" option (kept using the integrated graphics instead)
• Adding the following code to my configuration.nix:

        
    hardware.graphics = {
    enable = true;
    enable32Bit = true;
    };
    
    

• Launching the game from bottles gui, after using the enviroment variable DRI_PRIME=1 DXVK_FILTER_DEVICE_NAME="AMD Radeon R5 M445 Series (RADV ICELAND)" and enabling/disabling the "use discrete gpu" option (it told me that I don't have directX11 installed, but the game should run without it according to steamdb)
• Setting KDE power profile from "Balanced" to "Performance"

Note that I can launch native apps with discrete gpu by typing in the terminal DRI_PRIME=1 $program_name, where $program_name is the name of the program I want to launch (like SuperTuxKart).

Is there a way to launch bottle apps with my discrete gpu or at least run all of my apps with my discrete gpu? Some extra related links I found, but didn't solve my issue:
