No. The IRS has suspended some deadlines, but they have not changed the actual rules and laws for filing tax returns. You can apply for an ITIN by mail by mailing a form W7 and all the required proofs to the address in the form W7 instructions. If you print your tax return, and sign it, and mail it along with the W7, then after the IRS issues the ITIN, they will process the tax return. You should use a mail service with tracking and proof of delivery.
