Why exactly would Trump’s tariff dividend increase inflation, however certain economics argue UBI isn’t particularly inflationary?

Of course, I know not every economicist is in alignment on the effects of UBI, however I just want to hear the reasons for why the two policies differ.

I understand tariffs are inherently inflationary, but I'm not quite sure I understand why the would mean specifically the dividend itself would also be inflationary, or at least noteworthy in increasing inflation.
