After some testing I've updated the first post
I have a question: boosting GPU clocks can improve dynamic resolution in handheld mode to push the game more often to 720p?
PERFORMANCE BOOST
The Legend Of Zelda: Tears Of The Kingdom
SYS-CLK
HANDHELD + CHARGING
CPU: 1581 MHz
GPU: 768 MHz
MEM: 1600 MHz
DOCKED
CPU: 1581 MHz
GPU: 921 MHz
MEM: 1600 MHz
This configuration provides general improvement on game's performance stability while playing in handheld mode...
When I format the Switch using the official initialize option, then I have to use again the RCM JIG to hack the Switch? Basically I will have to begin from scratch, as the Switch was never hacked?
Why you recommand me to backup my NAND?
Do you think that an initializing process will solve the problem? What happens if I do that? All files, games and data disappers, but then I have to install Atmosphere again?
How did you solve the Daybreak FW installation issue? I've also get the same error here:

I'm using a microSD->USB adapter. I've used the same files with the same adapter (on a different microSD) to update another Switch and the files worked well. So I think that the files are not a problem and neither the USB adapter. Maybe the microSD has some issues... I've already tried to format...
I've tried to set that DNS, but it gives me the same error
EDIT: I've also removed the hosts.txt file from the Atmosphere folder which was blocking connections to Nintendo servers, but it doesn't work...
