Default USB-C monitor is not working

Hi everyone! I'm here because i don't know what to do anymore!
I have a laptop with one HDMI output and 1 USB-C connector. I need to connect a second monitor with the USB-C port, using an adapter to HDMI.
Following the arch wiki steps, i'm stucked at
xrandr --setprovideroutputsource 1 0
This happens because my Xrandr show me just ONE provider: INTEL. (optimus-manager set to intel)
xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x48 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel
It's valid to say that displaylink.service is running and I'm using the EVDI driver as you can see above:
systemctl status displaylink.service
● displaylink.service - DisplayLink Manager Service
     Loaded: loaded (/usr/lib/systemd/system/displaylink.service; enabled; vendor preset: disabled)
     Active: active (running) since Thu 2020-12-03 20:05:32 -03; 9min ago
    Process: 3470 ExecStartPre=/sbin/modprobe evdi (code=exited, status=0/SUCCESS)
   Main PID: 3471 (DisplayLinkMana)
      Tasks: 14 (limit: 18826)
     Memory: 1.6M
     CGroup: /system.slice/displaylink.service
             └─3471 /usr/lib/displaylink/DisplayLinkManager

dez 03 20:05:32 pedro systemd[1]: Starting DisplayLink Manager Service...
dez 03 20:05:32 pedro systemd[1]: Started DisplayLink Manager Service.

dkms status
evdi, 1.7.0, 5.9.11-3-MANJARO, x86_64: installed
I'm using the Optimus-Manager, and I tried DisplayLink with the 3 options provides by him: INTEL / NVIDIA / HYBRID and any of them works.

I already create a file at /usr/share/X11/xorg.conf.d/20-evdidevice.conf
Section "OutputClass"
	Identifier "DisplayLink"
	MatchDriver "evdi"
	Driver "modesetting"
	Option  "AccelMethod" "none"
I tried to follow the guide to create a file 20-displaylink and disable PageFlip for modesetting but when I do this, the only provider that shows is "modesetting" and one more time I can't xrandr --setprovideroutputsource 1 0

I really can't proceed anymore, please help! I'm on KDE Manjaro currently on kernel 5.9
I know that this is a UBUNTU driver, but I think this is the only way to do this. In windows 10 it works!!
