New Income Tax Exemption Scheme(AY-2021-22) applicability for freelance professional (44ADA)

I am a freelance professional filing my tax under 44ADA - 50% as income/profit scheme. After reducing earnings by 50%, currently under 'old' tax regime, I apply the old tax slabs to compute my tax liability. Can I opt for new tax slabs (without exemptions) announced on 1-Feb-2020 as a 44ADA professional from AY2021-22 OR are the new slabs only for 'salaried' individuals?
