Negative. From Post #59 (links from which I recommend careful study first) the Lineage install page includes
Warning: Before following these instructions please ensure that the device is currently using Android 12 firmware.
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!
If your current installation is newer or older than Android 12, please upgrade or downgrade to the required version before proceeding (guides can be found on the internet!).
Quoting Week 35, 2023 : Development and Testing Updates
/e/OS T builds
Status :Build and testing
Team is working on adding firmware along with the T builds. This will make it easier for users to flash the builds without having to flash the stock ROM first.
Vendor blobs refers to largely proprietary parts which we are used to seeing only in the manufacturer’s firmware, now seen in the T builds.
The output above from payload-dumper-go suggests that the /e/OS Android T ROM contains firmware parts not previously seen in /e/ ROMs.
