you are free to do whatever you want...
You can even disable the rsyslog service completely and have no logging
at all.
However, turning off logging is not a very smart approach, and thinking
you can turn logging on again "when it's needed" is imho rather naive
thinking. When an application (and it may even fail to restart) fails,
you may no longer be able to find out what has caused the issue without
logs.
You can use RAM (temporary file system) as suggested by @vince, you can
move the logs to a remote server (e.g. NAS) etc., but switching off
logging completely is nothing a professional IT person would recommend
you could also use a SSD disk instead of a microSD with your RPi or a
SLC microSD card if you want to avoid wear out of your SD card ...
I'm using both approaches for years now with my RPi's - and have my logs
available in case they are needed 😎

Thank you. I'm using log2ram so I think it has the same effect. But I
think that some mechanism to completely turn off logging does/should
exist. I can always turn it on if needed.
 I don't know if it is good approach but I've used
"disable_existing_loggers = True" directive in weewx.conf and log
aren't generated - or I can't find them :)

I just log to tmpfs (essentially ramdisk) and it is not an issue
for me.
Add this to your /etc/fstab and reboot
#---- put logs and tmp dirs in ramdisk ---
tmpfs      /tmp       tmpfs
defaults,nosuid,mode=0755,nodev,noatime  0    0
tmpfs      /var/log     tmpfs
defaults,nosuid,mode=0755,nodev,noatime  0    0
tmpfs      /var/tmp     tmpfs
defaults,nosuid,mode=0755,nodev,noatime  0    0

Note that the result here is that you will lose 'all' logs when
you reboot, but the upside is it never writes to SD card. Â In this
configuration your pi SD is close to read-only.

Hi WX users.
I'd like to ask about logging in Weewx (I'm using version
4.10.2). To make a long story short, I'd like to completely
turn off logging by Weewx - because I'm using Raspberry Pi
with SD card and want to minimize write operations as much as
possible.
I've read article on wiki
(https://github.com/weewx/weewx/wiki/WeeWX-v4-and-logging) but
do not clearly understand new way of control logging. I'd like
to have simple switch in weewx.conf, for example
"completely_disable_logging = True" or something similar. Is
there some switch in [Logging] block as I see it in wiki? If I
change "disable_existing_loggers = False" to
"disable_existing_loggers = True", will I get the expected effect?
