If the funds are disbursed directly from the charity on project expenses (a charitable purpose), rather than to the person for their general use (not a charitable purpose), it is possible to avoid taxes. For example, EA charities hiring personal assistants for academics.
The individual receiving the grant has to pay taxes on it, so the net benefit may be somewhat less than you’re anticipating.

I am aware but the benefit is still quite large.
