The #7 BMW M4 GT4 of Mohammed Al Saud, Diego Menchaca, Jean-Baptiste Simmenauer, Jens Klingmann, and Dries Vanthoor claimed top honours.
Herberth Motorsport had been leading in the last hour but made a late fuel stop with 20 minutes to go, allowing Vanthoor to cross the line 21 seconds ahead in the Team WRT car.
Team WRT claimed its second consecutive win in the Dubai enduro, while Herberth Motorsport held onto second.
The #10 Porsche 911 GT3 R was in contention for a podium for much of the 24-hour distance, though bled time in a Code 60 period.
A fourth-place result for the Groves is an improvement on their sixth-placed effort last year.
“The process is always finishing the race, which was the main goal to do that,” Stephen Grove told Speedcafe.com.
“There was one Full Course Yellow that really hampered us, we probably would have been on for a better result, but fourth is good.
“It's a 24-hour with no Safety Cars, it's Full Course Yellows so you don't have the ability to make up time, so really it's a 24-hour sprint race.
“For Anton to spend so much time in the car and do lap after lap for a long period of time, it will only do his driving a world of good.”
It marked De Pasquale's second race in GT3 machinery, with the Dick Johnson Racing Supercars driver also set to join the Grove father-son combination at next month's Bathurst 12 Hour.
“Firstly really cool to be back here in Dubai with the Groves and Earl for another Dubai 24,” De Pasquale told Speedcafe.com.
“It was a hectic race, had some really good speed and we were in with a shot for a large portion of it.
“To finish a 24-hour race is really cool and to be just shy of a podium is also really good.
“It's very different when it goes to the Code 60 — you can be at the wrong side of the track and miss the pits and all this kind of stuff which happened to us a few times and I'm sure it happened to other people heaps of times throughout the race.
“There's a whole different strategy, sometimes it just falls your way and sometimes it doesn't, but it's really a time trial to the end and judging those unknown windows.
“It's something very different to what we normally do but it's still heaps of fun.
“I'm sure we'll be coming back and trying to go better in the future but we've got Bathurst next; 12 hours around there back at home and heaps of miles in the car so looking forward to it.”
The 2023 Bathurst 12 Hour takes place from February 3-5.
