No. E-AC-3 is a codec. However, at higher bitrates (768kbps+), it is incredibly difficult for the human ear to tell the difference between it and a lossless track like TrueHD or PCM.
You will get a massive TrueHD track. If you re-encode that for a Plex server to save space, you would transcode it to EAC-3 (usually 640 kbps for 7.1 or 768 kbps for Atmos) to keep surround sound at a reasonable file size. You will get a massive TrueHD track

However, new audio coding standards, such as Dolby Atmos and MPEG-H Audio, are emerging, offering even more advanced features and improved sound quality. As the audio landscape continues to shift, it will be interesting to see how EAC-3 adapts and evolves to remain relevant. but explosions are loud." However
