Tamworth boss Dale Belford says they will remain professional despite already having been relegated.
He told the local press: "We owe it to the league to stay professional and Hereford still have things to play for so we need to make sure we are fully focused. The same goes for Dartford on Monday. We can still have a say in matters throughout the league.
"I hope the supporters come out and back us on Friday. I understand their frustration right now but we have a young set of lads here and they need the crowd behind them."
Defender Ben Richards-Everton echoed his manager's sentiments, adding: "We have just got to remain professional. We have three games left and we are not going to just lose interest because we are down.
"We can still have a big say in what happens with the teams around us, like Hereford and Dartford. So the talk in the dressing room is still about getting three points on the board in every game and that certainly won't change."
