There’s no evidence to support that. Best evidence is that our ancestors for the longest time were likely opportunistic omnivores. Plants of course were a large part of the diet, but looking back to about 3.9 mya meat was on the menu.
They overwhelmingly ate more plants than meat we can safely presume. Meat they could get would be mostly insects, and an already dead or sick animals. Later when they came out of the trees shellfish.
Yes scavenging for meat is generally considered a very important part of human evolution. Our stomachs are particularly acidic when compared to other great apes. This is believed to have evolved due to a high consumption of scavenged meats.
You are right though plants generally did form a large portion of our and our ancestors diets.
Important to note that as our brain size increased it did correlate with increased meat consumption as well. This all goes into calorie densities, available nutrients, and evolutionary pressures.
