Here's my personal opinion
For the current situation, yes we need strict lock down to control the situation. This need to be very strictly implemented using armed forces and police. Apart from essential services persons others should not allowed to go out. Even the essential service personnel need to undergo antigen tests daily to stop spreading virus through them.
Once lock down lifted we need to strictly maintain social distancing and need to wear masks. Every shop required to provide hand washing facilities. Again we can use armed forces with the help of police to enforce this. Anyone braking the law including people who don't wear masks properly need to fine at least Rs500 per offence.
Any public gatherings need to strictly limit and if allowed for functions in limited capacity they need to ask vaccination certificate from each and every attendee. Government need to fine heavy penaltys to any venue that break these measures.
Companies legally required to do antigen tests every week. Government can provide these test kits at cost. It's cheaper than lock down and related economic consequences.
