Yes.
Buddha is an avatar of Lord Vishnu. He deluded asuras by refusing Vedas.
Then in the Kali age, the lord was born in the Kikatas as Buddha. He deluded the asuras and flouted the Vedas.
Yes. God Vishnu took two incarnation and taught anti-Vedic philosophy.
As per Agni Purāṇa, Vishnu incarnated as Buddhism's Buddha and Jainism Tirthankara, and taught anti-Vedic (heterodox) nâstika doctrines.
Chapter 16 - Buddhādyatārakathanam, Agni Purāṇa
मोहयामास दैत्यांस्तांस्त्याजिता वेदधर्मकम् ।
ते च बौद्धा बभूवुर्हि तेभ्योन्ये वेदवर्जिताः ॥ ३ ॥
आर्हतः सोऽभवत् पश्चादार्हतानकरोत् परान् ।
एवं पाषण्डिनो जाता वेदधर्म्मादिवर्जिताः ॥ ४ ॥
- 3 & 4. He (Vishnu) deluded those demons. Those, who had abandoned the path laid down in the Vedas, became the Bauddhas and from them others who had abandoned the Vedas. He then became the Arhat (Jaina). He then made others as Arhats. Thus the heretics came into being devoid of Vedic dharmas.
