The UK and EU will hold their first bilateral summit since Brexit on Monday, described by Prime Minister Sir Keir Starmer as a "really significant moment".
Sir Keir is expected to announce a deal when he meets European Commission President Ursula von der Leyen and European Council President Antonio Costa.
Announcements around trade and security have been expected to include British access to a 150 billion euro (£125 billion) EU defence fund, in what could be a boost for UK defence companies.
But reports suggest there could also be agreements on allowing British travellers to use e-gates at European airports, cutting red tape on food exports and imports, and setting up a youth mobility scheme with the EU.
Describing talks as in "the very final hours", Thomas-Symonds said he was driven by "ruthless pragmatism" and focused on jobs, lower household bills and stronger borders.
The minister also said the government would assess whether to contribute money to EU projects on a case-by-case basis, saying it would "consider each one on its merits".
Asked whether he was confident British travellers would be able to use EU e-gates at European airports, Thomas-Symonds said: "I'm certainly pushing for people to be able to go through far more quickly.
"I think we can all agree that not being stuck in queues and having more time to spend, whether it's on holiday or work trips, having more time to do what you want ... would be a very sensible objective."
The minister said he was confident about a deal on food, but added "nothing is agreed until everything is agreed".
He added: "We know we've had lorries waiting for 16 hours, fresh food in the back not able to be exported because frankly it's just going off, red tape, all the certifications that are required, we absolutely want to reduce that."
