不可以
因为enjoy是动词 动词前否定只能助动词do,而did是do的过去式,
当一个词是形容词时,如good,才能用BE动词am,is,are
如 I am a good student.

did为过去式，是在陈述过去发生的事。而am为一般现在式，陈述现在或经常发生的事。俩着都可以，只是时态不同罢了。

一个短句中只能有一个动词（情态动词用法除外），be动词(was)和实意动词（enjoy)连用时，实意动词就应变为非谓语动词中的ing形式，也就是进行时.
did为do过去时，帮助实意动词完成否定和强调。
因而第二个句子根本不对

enjoy是实义动词，am is are都是be动词，他们是不能同时存在的
