They are to resist tinkering with the team because they are only playing two warm-up matches, which are threatened by continued heavy rain.
Normally, all squad members are given some competitive action.
Michael Vaughan said: "We'll be trying to play our best players and get them into form for that first Test match."

England are set to play their first warm-up game against a BCB President's XI on Sunday and the first Test is scheduled for Dhaka on 21 October.
England's preparations have been hampered by the torrential rain, which forced them to practice indoors on Thursday.

"If he gets
an opportunity to play I hope he bowls like he did for Kent this summer because
he's taken a number of wickets for them over the last three years."
