Code:

# zypper ref
# zypper in droid-config-f5122 droid-config-f5122-bluez5 droid-config-f5122-flashing droid-config-f5122-policy-settings droid-config-f5122-preinit-plugin droid-config-f5122-pulseaudio-settings droid-config-f5122-sailfish droid-system-f5122 droid-hal-version-f5122 pattern:jolla-configuration
# zypper remove droid-config-f5121 droid-config-f5121-bluez5 droid-config-f5121-flashing droid-config-f5121-policy-settings droid-config-f5121-preinit-plugin droid-config-f5121-pulseaudio-settings droid-config-f5121-sailfish droid-hal-version-f5121
# reboot

You need Developer Mode and zypper installed. Each command starting with "zypper " needs to be on one line. The zypper install will ask to resolve a conflict involving droid-system-f5122 and droid-system-f5121, choose to install the f5122 version and remove the f5121 one.
I basically searched all packages with "f5122" in their name and replace the corresponding "f5121 ones.

After the Reboot my 2 SIM-Cards are detected without any manual changing of the configs, and the "About Device"- Dialog in the Setting states product as "Xperia X Dual SIM"

I only did some brief testing, but everything does seem to work fine. CSD tests als show no apparent failures.

And again, this is a "hacky" method I tried on my device and which seems to have worked. It might develop long term problems or not work on your device. Make sure to have backups available and be ready to reflash your device if anything fails!
