The 21-year-old New Zealander was drafted in by the Red Bull-owned team after Australian Ricciardo broke his hand in practice for last month's Dutch Grand Prix, missing that race and the Italian Grand Prix.
Ricciardo, who returned to the paddock ahead of this weekend's Singapore Grand Prix to be with the team engineers, could also miss the Japanese round at Suzuka on Sept. 24.
And I don't think I can settle for anything less," Lawson told reporters.
Lawson has been racing in Japan this year and has competed previously at Suzuka.
"My dad, he promised me like every year from when I was seven years old that he'd take me to the Singapore Grand Prix, and we never could go," he said.
