I have read some topics about turning off log display during kernel startup. Following the instructions inside, I have successfully turned off most of the log displays during UEFI and kernel startup. However, after burning the image, there will still be some log displays in the stage where I configure my username and password. After I finish configuring, I will no longer see these logs after restarting. I cannot find a similar method to close logs. Please guide me to close them. During the startup phase, I need to disable all log displays

In fact, the above image is the result of changing console=tty0 to console=ttyTHS4. If you simply delete console=tty0, more logs will appear, as shown in the following image
Have you tried to remove CONFIG_FRAMEBUFFER_CONSOLE in kernel config?
After verification, this modification is valid, but I would like to know why
What do you mean about “why”?
That kernel config (CONFIG_FRAMEBUFFER_CONSOLE) is used to decide if the framebuffer should be enabled.
