Hi Dharmesh and welcome
As far as I know, situational awareness does not need any training; the burden is put on technology rather than the pilot
In my view SA does require significant training to prevent the pilot fixating on one instrument or activity. SA requires the pilot to constantly divide their attention between tasks to achieve that 'global' view of their surroundings. The extent of the global view changes depending on your activity. VFR flying in uncontrolled airspace requires constant awareness of your navigation, engine/fuel condition, a/c attitude, R/T and knowledge of what is occupying the near sky in virtually a 180 deg area round, above and below you. Doing all these activities to a reasonable level of frequency and diligance without impinging on the effectiveness or efficiency of the others is definately a learnt skill for most people (me included).
