It's hard to know what is and is not a no-name brand if you're new to knives. There's no discernible difference (on the surface) between a pop-up vendor who just re-brands cheap knives and a true manufacturer. One of the best ways to start figuring this out is to not shop on Amazon. A dedicated and trusted knife store like: BladeHQ, KnifeCenter, WhiteMountainKnives, KnifeJoy, KnivesShipFree, and a few others, will give you the best info. You will find better ways to filter and budget options that are much better choices. But it's still overwhelming.

If you have a specific style of knife you're looking for, and you're not sure if it's a good or bad brand, I'd start by asking here (or over in pocketknife@lemmy.world

As other's have said, there are some good budget brands out there for well under $50.
