Neopixel Matrix SK6812

I think to make some sort of a matrix display with SK6812 LED. Adafruit Neopixel lib should work just fine. But there are some things about designing it that are not clear to me.

I would like to make it in some 10x15 matrix. According to a datasheet each of the LED needs a cap. I could put a cap on the other side of the PCB. But, do I really need a cap for any of them, or it can be arranged somehow to use less of them. One bigger for a row, or something like that. If you take a look at some of the Pimoroni packs for RP2040, they do not use a cap for every LED.

I believe I could use those 30 on one data pin to some MCU without a problem. Or I am wrong.
