@jmuccirelli --
Unfortunately, I suspect that if the "Payer" shown on your 1099-NEC has a California address, the California tax board will take it that you are providing your services to a client located in California. But remember that you're not required to file a non-resident CA tax return unless your income exceeds California's filing requirements for non-residents, which you can find here:
