When purchasing 'as-is' the seller is expected to do no repair. The buyer has the right to an inspection period, however, and may cancel the contract if the inspection is not acceptable (i.e. unforseen needed repairs). The inspection period must have been met, however, and written notice of cancellation provided to the seller in the specified timeframe. In the truest sense, one does not 'override' the other, they compliment each other and spell out the expectations of what the buyer and seller will do. If the inspection contingency or as-is represents an addendum to the contract, the addendum will carry the greater weight.
