Impossible to default to change bluetoothctl configuration on 2nd controller and saving+applying

[yhilg]

Using the latest release with both an outdated(onboard) and modern(USB) adapter it is only possible to select the modern and not actually have it used.

Switching from onboard to USB is OK:

[gamer@chimeraos ~]$ bluetoothctl
Agent registered
[Wireless Controller]# list
Controller 80:30:49:2D:01:AC chimeraos #1 [default]
Controller E8:48:B8:C8:20:00 chimeraos 
[Wireless Controller]# select E8:48:B8:C8:20:00
Controller E8:48:B8:C8:20:00 chimeraos [default]
[Wireless Controller]# list
Controller 80:30:49:2D:01:AC chimeraos #1 
Controller E8:48:B8:C8:20:00 chimeraos [default]

It connects well with both of my bluetooth controllers:

[Wireless Controller]# scan on
Discovery started
[CHG] Controller E8:48:B8:C8:20:00 Discovering: yes
[NEW] Device A4:C1:38:7A:99:5A ihoment_H6127_995A
[NEW] Device A4:C1:38:9F:36:F8 ihoment_H613D_36F8
[Wireless Controller]#

But I sadly believe that ChimeraOS ends up never using them because when I quit and come back, the outdated controller is back to default:

[Wireless Controller]# exit
[gamer@chimeraos ~]$ sudo bluetoothctl
[sudo] password for gamer: 
Agent registered
[Wireless Controller]# list
Controller 80:30:49:2D:01:AC chimeraos #1 [default]
Controller E8:48:B8:C8:20:00 chimeraos 
[Wireless Controller]# 

I understand my easiest work-around would be to disable this onboard controller but this NOT an option from the BIOS.
