It seems the way they plan to crack down on the fireworks is to address the suppliers who bring the fireworks into the city in the first place. I don't see any mention of trying to crack down on people who are setting them off.

“Each summer, we look forward to the right kind of fireworks … but we also know there’s a real problem with the wrong kind of fireworks,” de Blasio said during his daily virtual press conference.
“Illegal fireworks are noisy, they disrupt the peace in neighborhoods, but they can also be dangerous, and we have to understand how important it is to ensure that illegal fireworks are confiscated, so they can’t do harm to people in communities.”
In June 2020, 8,967 complaints of illegal fireworks were reported to the city’s 311 system from June 1 through June 21, which represents more than 320 times the 28 such calls made during the first three weeks of June 2019.
The mayor said law enforcement will “go after” people taking fireworks from other states, in order for the Big Apple to have a calmer summer compared to last year, when fireworks were set off nearly every night in the five boroughs.
“We’re going after the people who bring the fireworks into New York City to begin with,” Hizzoner said.
“We’re getting right at the source. … This is what is going to help us have a safer summer.”
The fireworks task force will have 32 officers, including 12 FDNY fire marshals and 10 deputy sheriffs, according to Sheriff Joseph Fucito. They will work in cooperation with state police in New York, New Jersey and Pennsylvania, said Fucito.
“What the task force is looking to do is to develop information on who the major suppliers are,” he said Wednesday during the morning press conference.
“We’re going to look to interdict these illegal fireworks as they come into New York City — so, if we can get them before they get into the city, it’s a good thing for the people. We also want to target the sellers who peddle the illegal fireworks.”
