OK, but, I search in Octopi and still appears
lib32-opencl-nvidia--390xxx
So, can I remove this and install again nvidia 470 drivers and dkms? what is the command in order to install all correctly?
╰─λ DRI_PRIME=1 glxinfo -B | grep "OpenGL vendor string"
libGL error: glx: failed to create dri3 screen
libGL error: failed to load driver: nouveau
OpenGL vendor string: Intel
Any help?
Sorry, again, please read the wiki.
DRI_PRIME is used if you have an NVIDIA GPU without the proprietary driver installed.
Not needed.
Please show this output:
pacman -Qqe | grep nvidia
Please also show:
ls /etc/modprobe.d/

But, all that, after I remove nvidia-390xxx wwith octopi, .... but:
If i want to remove nvidia-390xxx it seems that will remove also 470...
And all another important stuff...
Hardware settings still shows 390:
... any help?

Now, reboot?
Yes, go ahead. 
That looks fine, just check inxi -G to confirm you have the driver loaded. Then launch your apps with prime-run.
If you really need to see the checkbox in Hardware Configuration, I think you need to set this one up:
sudo mhwd -i pci video-nvidia-prime-render-offload
Those are fine. These packages are all related:
They are part of the auto-install option. You don’t need to try to remove them or do anything with them.
OK, this shows inxi -G:

What can I do?
Just stop, is what I think you should do. The correct drivers are installed. The struggle is over. These additional efforts are more likely to break something than provide any benefit.
Go ahead and enjoy your computer now.

OK, thanks @BluishHumility all my gratitude to you, @filo and @SGS ...
A last couple of questions...
How can I activate correctly the profiles of nvidia:
ERROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file
should have been installed along with this driver at
/usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will
continue to work, but values cannot be prepopulated or validated, and will not be listed in the help
text. Please see the README for possible values and descriptions.
... and, how I run a game in lutris with NVIDIA in order to switch correctly to NVIDIA GPU?
