No, backgrounds cannot be removed from regular Instant Avatars. To do so, you would need to upgrade to Instant Avatar Finetune, which utilizes the AI matting feature to remove backgrounds. However, please be aware that the quality of background removal depends on the quality of your footage. Factors such as obstructions in the background or uneven lighting can affect the effectiveness of AI background removal. Alternatively, you can also consider purchasing the 'Studio Avatar', which offers professional-level manual background removal.
