Is The Goldfinch LGBT?

Could you please clarify whether the novel "The Goldfinch" by Donna Tartt explores themes related to the LGBT community? While the novel is renowned for its intricate plot and rich character development, it is not immediately apparent whether it delves into issues surrounding sexual identity or gender roles. Is there any evidence within the text that suggests the involvement of LGBT characters or themes? Are there any explicit or implicit references that might indicate the novel tackles this subject matter? I'm interested in understanding whether this aspect of the novel has been discussed by critics or readers and what their take on it is. Thank you for your clarification.
