Should I remove “await” keyword to increase response time?

I’ve database of users where they have created their team. and other document for storing racers.

each user can create a team of 6 racers.

but the problem is that I’ve 50k users and using the below code to remove a racer from their team if Admin deleted it from Racers Document.

I’m using express.js and mongoose

team is an array of object which has racers name, it’s shortCode and unique identifier.

async function delete(req, body){
    // code to validate users input
    await Users.updateMany({'tema.shortCode': 'HAM'}, { $pull: {'team.shortCode': 'HAM'}})

}

I’ve seen that response time decreases if i remove await keyword. But is it recommended to do that.
