Is “Taizu's deathbed decree to pass the throne and grant the golden tablet” true?

In the fifth chapter of The Generals of the Yang Family, it is described that when Taizu was dying, he followed his mother's deathbed decree, summoned Guangyi to attend him, and personally entrusted the succession, while also granting a golden tablet to his son Dezhao: 'Because he followed his mother's deathbed decree, he summoned his younger brother, the Prince of Jin, Guangyi, to attend him, and entrusted him with the affairs of the future, saying: "I observe that you walk like a dragon and step like a tiger; in the future you will surely be a peaceful emperor. But you must treat your nephew Dezhao well." ... Taizu then called his son Dezhao and said: "It is not easy to be a ruler. Now I pass the throne to your uncle, to take over the toil for you. I now grant you a golden tablet, so that if there are any treacherous ministers in the court, you may execute them without prior approval."' In the official history, History of Song, Annals of Taizong, Volume 1, the process of Taizong's accession is only recorded as: 'In the tenth month of the ninth year of Kaibao, on the day guichou, Taizu died, and the emperor then ascended the throne.' There is no mention of a deathbed instruction or the granting of a golden tablet to Dezhao. Through fiction, the novel endows Dezhao with special power.
