Yes, and furthermore, I believe we should!
Here I’d like to distinguish between two things:
- The communal Eid prayer offered in an open space (or mosque) with the subsequent sermon,
- Offering two units of prayer for the special occasion of Eid.
Now of course, for those living under lockdown, unfortunately the first is unfeasible. But this does not preclude the second, and I believe it is virtuous to perform two units of prayer for the special occasion of Eid, and it is what God wants from believers.
