I think some inflation will happen but not dramatically in food and clothing. We do not have many naked and starving people in America. It’s the premium consumer goods that will see higher demand - think dishwashers not Chanel.
Many types of food in America are massively subsidized, including dairy[1], beef[2], and corn.
Government policies can certainly drive down prices. Direct price controls don't work, but subsidizing production most certainly works.
Though an economist would argue that a dollar saved at the market cost tax payers more than a dollar to get, due to inefficiencies, counter argument is that people who are poor pay less taxes and benefit more from reduced food prices. (At which points arguments about corn subsidizes and long term harm to the health of the citizenry are brought up.)

UBI fundamentally does not solve the problems that:
a) some people do not want to live next to some other people, and are willing to pay extra for that privilege - now they have even more money to use for that purpose,
b) in the most expensive regions, demand exceeds supply a lot.
I even think that a vast majority of UBI would, at the end, accrue to landlords.
