Taking this sentence as an example:

> 納入した学費は、理由の如何｛を問わず/に関わらず｝返却しません。

I always have a hard time knowing how to read 如何; いか, いかが, even どう or いかん
sometimes..

I've checked if the question was answered previously, I hope I didn't missed
it!

Question about how to read 如何
In the sentence you gave it is functioning as a noun, so its reading is
[如何]{いかん}.

> ❶［名］事の次第。なりゆき。ようす。「理由の―によっては」「事の成否は君の協力―による」

Recognizing from context the part of speech 如何 is functioning as (noun,
adverb, adjectival verb) is helpful as a first step. Also, recognizing if it
is part of a set phrase e.g. [如何]{どう}あっても, [如何]{どう}致しまして, [如何]{いかが}なものか,
[如何]{いかん}せん, [如何]{いか}に should get you there in most cases.
