How to prevent automatic mounting of USB device

With dconf-editor, I tried setting the following to false:
org.mate.desktop.media-handling.automount
org.mate.desktop.media-handling.automount-open
org.gnome.desktop.media-handling.automount
org.gnome.desktop.media-handling.automount-open
Still, any USB drive is automatically mounted.
How to prevent that?
This is a huge problem because I want to clean a filesystem from a micro SD card. After it automounts, "umount" returns "Error finding object for block device 0:110" so I cannot unmount it. I am guessing this filesystem has a problem but automount prevents me from doing anything and may even be making the problem worse.
After it automounts, "umount" returns "Error finding object for block device 0:110" so I cannot unmount it.
And with the following command, where /dev/sdb1 is to be replaced by the actual partition?
$ udisksctl unmount --block-device /dev/sdb1
Magic Banana comes up with the most interesting & useful commands, such as udisksctl
for which I can find a brief man page, but which apt-get install cannot find, whether I request
udisksctl or just udisks. There's a disks package that I use frequently to capture
UUIDs. Are these mystery packages bundled with a larger package ? After looking at info udisks
I'm cautioning myself to be careful !
Several years ago I found a 5-1/4 inch floppy drive controller that connects through a USB port,
but its use requires setting up loop devices over & over as I progress through a pile of didks
written with an IBM PC/XT (which I still have ...). Hence, my interest in udisksctl.
Try: apt-file search udisksctl
Jxself set me off with his suggestion to tryapt-file search udisksctlbut I shortened that toapt-file search udiskswhich brought me a list of over 500 possibilities, which I cut down a little with
awk '{print $2}' apt-file-search-udisks-family-commands.txt | grep "\.html" | sed 's/\//\t/g'| awk '{print $6}' | sed 's/\.html//g' > apt-file-search-udisks-family-commands.html.txt(attached) which is a list of html files from which I picked the one pertaining to udisksctl which led full circle to this discussion:https://forum.artixlinux.org/index.php/topic,2811.15.html.

Thanks for the suggestion.
As I needed the system with the SD card to run, I did not wait for answers to physically remove it even though it was mounted and I used my laptop on which there is no automount (perhaps because I use fvwm only without mate) to check the SD card.
From the manual on udisksctl, I see there is this udisksd and it is running when I have a mate session. Automount is probably a useful feature but it would be nice to at least have an easy way to turn it off. I'll check it a bit more.
EDIT: When I log in via the usual greeter and I have selected fvwm instead of mate, udisksd is running and so is gvfsd (I looked at that because of the link indicated by amenex). So I don't know what programme does the automount after opening a mate session. Perhaps I could monitor dbus messages to find out but I need to understand dbus details first (unfortunately).
