1. Cold plunge - high but transient (last for hours). I do it in the morning, after my shower - start the day off right.
2. Exercise - short-term: increases dopamine, serotonin, and a bunch of other good stuff; long-term: increases dopamine receptor density.
3. Caffeine - while doesn't technically increase dopamine, it blocks adenosine receptors which indirectly increases dopamine signalling. But habitual use blunts the effect.
Other less acute things are: good sleep and lots of sunlight esp early in the day.
