Depends your field I would say, example I'm working in voice recorder field yeah you can remote access via internet as long with internet,

but if client site whatever reason data failure still need drop by recover everything then wait the software department before they do it at office now they're WFH remote in get the job done, whatever they need simply remote office server pull data they need and transfer over to client, plus our internet now unlike old times slow until need few hour to transfer 1gb data

For safe boss ask client issue me a letter attached with my current company letter for me to come and there are no issue for traveling from 1st MCO until now , my experience every road block they don't ask me Much show letter he take a look,and look at my back sit full of tools and let me go also most of the time boss only ask me go die outside the rest stay at home or WFH
