No.
The Maw's Grave: "You do not gain or lose Honor."
Do not: "A phrase meaning that a certain occurrence (for example, losing honor) simply does not happen under the circumstances given; it is not negation and overrides effects that prevent negation."
The honour loss is not merely negated, it simply does not exist for a The Maw's Grave player; Determination does not help.
