As I said earlier, this behavior isn't autofs. Don't blame autofs.
autofs is a nice tool. autofs is easy to understand, enable and
disable.
To disable the auto-mounting of USB disks via udisks, you'd need to
set up a custom udev rule. Of course, it's hard to know which
existing udev rule is catching your disk, as you said, behavior is
different with an SD card than with a USB disk.
For CentOS6, the udev configuration for udisks is:
/lib/udev/rules.d/80-udisks.rules
... while in CentOS7, the udisks2 udev config is:
/usr/lib/udev/rules.d/80-udisks2.rules
You'd put the custom rule in /etc/udev/rules.d/.
These rules depend on the device name, vendor and model ID, drivers
used, etc. You'd have to write a custom udev rule either for that
particular device, or something more generic for that class of
device.
You might want to consider just disabling udisks{,2} entirely, if you
don't use the features.
