Jos Buttler has not played in the series so far as he has recovered from a calf injury while playing in The Hundred, in which the team is led by Moeen Ali.
The World Cup takes place in Australia from 16 October to November. 13.
“With regards to Joss (Buttler), he’s still off for a while, he’s not a player we want to risk at this level, so close to the World Cup, and it was a fairly significant injury that he had ,” Mott told reporters.
“So, he’s champing a bit for a game, but we’ll just try and see how we go and maybe in the last game or two we can give him a chance.”
The series is tied 2-2 with the fifth game to be held in Lahore on Wednesday.
Matthew Mott was full of praise for Dawson, who had a previous top score of 10 in the format and finished with 34 at a strike rate of 200 to battle things out during the heat.
“Getting wickets in the powerplays put us on the backfoot, a really good partnership to get us back in it,” he said.
“Liam’s knock was special. It took everyone by surprise, we didn’t think in our wildest dreams that we would get to that position. It just shows in T20 cricket that you’ve never done it.
Captain Moeen admitted that the England team lost the match under late pressure after Pakistan’s tense finish.
“Amazing game of cricket. It went both ways. It kept swinging. The crowd was electric for all four games here,” Moeen said.
“We thought we should have chased it down, I’m disappointed that we didn’t. We kept on losing wickets but stayed there.
“Brook played well again and Dos, the way he batted tonight was excellent. I’m sorry he couldn’t get us over the line. But these things happen.
“We felt we should have won the match. There is pressure and he bowled really well.”
