New/old SAT question for schools without score choice

As the title says, I have a question about sending my new and old sat scores to colleges without score choice. Last December I took the old SAT and scored a 1900. However, when I took the new SAT I ended up scoring 1510. For schools without score choice am I required to send the old SAT score? I don’t want to as I don’t think it reflects the student I am and is a very low for many of the colleges I will be applying to. Thanks to anyone who can provide an answer!
