It depends, if you have some essential resource where supply is constrained then you might expect inflation. On the other hand goods that are readily available like food or oil shouldn't see any significant difference.
All resources are constrained. Food production requires land which is constrained. No one dies from hunger this days. People receiving UBI will just start buying organic food which is going to increase its price. Rent prices will soar as well because of constrained supply. So do salaries. So do other goods. And boom - there goes inflation.
Why? What mechanism would drive that? In the West we already have more food available than we can reasonably eat. Margins in agriculture are wafer thin driven down by competition.
Compare that to property where there is a limited supply and people are constrained in what they can buy by their salary and ability to get a mortgage.
