Deactivate NTP via DBUS

I want to deactivate the NTP in the Host OS and only activate it manually (to avoid corruption of my RTC).

I found this line of code to query the timedatectl properties:

DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host_run/dbus/system_bus_socket \  
  dbus-send \
  --system \
  --print-reply \
  --reply-timeout=2000 \
  --type=method_call \
  --dest=org.freedesktop.timedate1 \
  /org/freedesktop/timedate1  \
  org.freedesktop.DBus.Properties.GetAll \

and I want to modify it to call the method SetNTP that i found the the timedated freedesktop documentation.

How do i modify the DBUS command to call the method SetNTP and how do I pass the parameter true or false?
