Almost all SIRE/OCIMF and/or CDI recommendations are based on current law.
You are wrong;
4 From the operational point of view, automatic interface with activation of the ship’s heading or track control system (HCS/TCS) is a superfluous function because SOLAS regulation V/19.2.2.3 requires the BNWAS to be in operation whenever the ship is under way at sea. This creates an inconsistency between SOLAS regulation V/19.2.2.3 and the “Automatic mode” provisions in the performance standard. In addition, from the technical point of view, it is noted that this issue is also addressed in the “note” to section 3.1.1 of IEC 62616:2010 – Maritime navigation and radiocommunication equipment and systems – Bridge navigational watch alarm system (BNWAS), which states:
- “NOTE: The Automatic mode is not suitable for use on a ship conforming with regulation SOLAS V/19.2.2.3 which requires the BNWAS to be in operation whenever the ship is underway at sea” .
5 Accordingly, as an interim measure and pending a revision of the Performance standards for a bridge navigational watch alarm system (BNWAS) – (resolution MSC.128(75)), the automatic operational mode, if it is available, should not be used.

You should have a valid reason for non-compliance with the bridge procedures, and any such occurrence should be properly reported. Ignorance of the applicable law and/or lack of skills would not be a good reason to do so.
According to MSC Resolution 232(82) there is a list of mandatory alarms and indications which must be active. You are not allowed to turn off the audible alarm, certified ECDIS does not even have such a technical possibility.
Of course you can always act like the captain of the tanker Genesis River. He, at the clear suggestion of the pilot, simply turned off not only ECDIS but also ARPA. Amazingly, this did not surprise officials, as well as many of our forum colleagues.
