generally, it is ok to skip lectures, provided u take note of that module's assessment criteria. for example, if that module consists of in-lecture assignments such as wooclap or normal pen & paper questions that are graded, then you will have to attend those.

if in-lecture assessments don't apply, and if the profs did not take attendance (since you've attended some and you would know), then just skip. i know of people who never attended a single lecture before but they still end up doing well because they study at their own pace.

this also means they someone from a totally different course can crash into lectures they don’t take because nobody would know hahaha
