Not yet. It is planned with no timeline, see Week 31, 2022 : Development and Testing Updates, section “OS OTA upgrades”.
This is a manual installation for now, including a data wipe by default … https://doc.e.foundation/devices/FP3.
Be aware that Android 11 (R) is still beta currently, so the Easy Installer would install Android 10 (Q).
Support for Android 9 (Pie) got dropped with /e/OS 1.0, see Week 29, 2022: Development and Testing Updates, section “End of official support for Nougat, Oreo and Pie” (although first announced in week 23), and Google dropped security update support for Android 9 months ago, so don’t expect much to happen anymore.
