Only Ubuntu 19.10 is installed on my computer. I just don't need the grub menu. I tried all the options I found for /etc/default/grub . It seems as if all my settings are being redefined elsewhere. Always a standard 30 seconds countdown. How to disable its display or adjust the countdown to the minimum value?

Try this...
sudo -H gedit /etc/default/grub
and change:
#GRUB_HIDDEN_TIMEOUT=0
GRUB_TIMEOUT=10
to:
#GRUB_HIDDEN_TIMEOUT=0
GRUB_TIMEOUT=0
sudo -H gedit /etc/grub.d/30_os-prober # find line 23
and change:
quick_boot="1"
to:
quick_boot="0"
sudo update-grub
reboot

You can't set a grub timeout of 0 but you can set a timeout of 0.1 which is hardly noticeable difference from 0. First use sudo -H gedit /etc/default/grub. Then locate these lines:
#GRUB_HIDDEN_TIMEOUT_QUIET=false
#GRUB_TIMEOUT_STYLE=countdown
#GRUB_HIDDEN_TIMEOUT=0
GRUB_TIMEOUT=0.1
Placing a # at front makes them a comment. Leave the rest of the line the same in case you need it again.
The last line is the timeout. Leave that as a regular command (no #) but change the value to 0.1.
Finally run sudo update-grub to compile the configuration file into a new grub boot script.
Bug in grub 2.04
You might be effected by a bug in Grub 2.04 but I couldn't find a reference with google search. If unable to fix you can downgrade to Grub 2.02 as described in this Q&A:
