This is the dictionary definition:

the deliberate and systematic destruction of a racial, political, or cultural group

And this is a quote from Israel’s Defence Minister, Yoav Gallant:

We will eliminate everything - they will regret it

He also said:

We are fighting human animals, and we are acting accordingly

And here’s a quote from Amit Halevi, a Likud member in parliament:

There should be two goals for this victory: One, there is no more Muslim land in the land of Israel … After we make it the land of Israel, Gaza should be left as a monument, like Sodom

Those are just some examples that I could find with a quick search, but they clearly show a will to perform a deliberate and systematic destruction of the Palestine people. Therefore since they act on those wishes I would definitely define it as a genocide.
