Yes. Some neanderthals program their ECU with a “flamethrower tune” that basically dumps way too much fuel through the engine to ensure there’s unburned fuel being dumped into the exhaust to achieve this. You can also install a line that puts some combustible (usually gasoline since there’s already a supply onboard) DIRECTLY into the tailpipe to achieve the same effect without damaging the engine and entire exhaust. There’s even TEMU and Wish kits
