how to stop auto updates in KNIME platform

The update for the KNIME Analytics platform (client) to a new version(4.7.8) is happening during the regular intervals of time (see figure 1) and the admin did not enforce it. However, the automatic update which happened, doesnt pick the latest version 5.2.

This auto update is happening only in Analytics platform.

Update in KNIME executor is not happening automatically, so the executor version is lower than the client (Analytics platform). Because of this, we are facing issues while opening dashboards for new workflows. (fig 2)

We want the update to happen, only when the admin does it.

Kindly share your ideas to stop this auto update.
