Experimental: Arm 1 - Participants will receive daily oral escalating doses of up to 800 mg of MK-1084 until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Experimental: Arm 2 - Participants will receive MK-1084 daily oral escalating dose of up to 800 mg plus pembrolizumab given as a 200 mg intravenous infusion once every 21-day cycle up to a total of 35 cycles (up to \~24 months). Treatment with MK-1084 will continue until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Experimental: Arm 3 - Participants will receive alternate formulation of MK-1084 until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Experimental: Arm 4 - Participants will receive MK-1084 daily oral dose plus an intravenous infusion of pembrolizumab (200 mg) once every 21-day cycle for up to 35 cycles (up to \~24 months). Participants will also receive carboplatin (per label) and pemetrexed (per label) once every 21-day cycle for the first 4 cycles.

Experimental: Arm 5 - Participants will receive MK-1084 daily oral dose plus an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle.

Experimental: Arm 6 - Participants will receive MK-1084 daily oral dose. Additionally, participants receive an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle, oxaliplatin (per label) for first 6 cycles, and leucovorin (per label) and 5-fluorouracil (per label) once every 14-days.
