No, assuming you don't have an actual health problem or nutritional deficit. If you think you might, see a doctor.
There are a LOT of different causes for low semen volume but average volume is only 2 to 5 ml or less than a teaspoon. When you see a LOT of semen in porn, it is almost always fake. Some men do produce a lot of ejaculate naturally just as some produce very little.
To increase your semen volume, be generally healthy (eat healthy, maintain a normal weight, exercise, get enough sleep, etc.) as a baseline.
Then there are two specific steps you can take to increase semen volume:
Stay well-hydrated.
Wait a full week or even longer before ejaculating.
Supposedly prostate massage can stimulate semen production but that hasn't been studied as far as I know.
