Did Lord Brahma have any incarnations as human?

According to the Skanda puran Brahma incarnated himself as the sage yajnabalkya in response to a curse from Shiva.

there was once a Brahmana named Kaushika who received a curse from the sage Mandavya that he would die at sunrise. As a result Kaushika's wife, who had magical powers, stopped the sun from rising. So the world was engulfed in darkness, and the gods turned Anusaya, wife of the sage Atri who was a mind-born son of Brahma, for help. Anusaya convinced Kaushika's wife to allow the sun to rise in exchange for Anusaya using her magical powers to save Kaushika's life. The gods were pleased with Anusaya and offered her a boon. Anusaya asked that Brahma, Vishnu, and Shiva should all be born as her sons. They agreed, and soon enough Brahma incarnated as Chandra the Moon god (AKA Soma), Vishnu, incarnated as Dattatreya, and Shiva incarnated as the angry sage Durvasa.

(copied from English translation of Markandeya Puran)

The moon, the stay of the life of all creatures, was born as the mind begotten son of the patriarch Atri. Well-pleased the high-souled Vishnu was born from his own body as the best of the twice-born, Dattatreya permeated by the quality of goodness. Incarnating himself Vishnu was born as the second son of Atri known under the name of Dattatreya who sucked the breast of Anusuya... Then was born Durvasa, a portion of Rudra impregnated with the quality of darkness. Thus Brahma, Vishnu, and Siva were born as her three sons. By virtue of the boon conferred upon her by the celestials Brahma was born at the moon, Vishnu as Dattatreya and Sankara as Durvasa.
