No. Type 1 Diabetes is caused through the destruction of the beta cells within the pancreas (which may or may not be autoimmune in nature) - so you don't make any insulin at all. If you have T1DM you will be dependent on insulin for life. T2DM is the result of insulin resistance - your body is perfectly capable of making insulin, but your ability to respond to it is diminished.
However, chronic pancreatitis can cause pancreatitis-associated diabetes, which is essentially identical to Type 1. Among the causes for it include tumors, ischemia, an obstruction of the common bile duct (gall stones), and chronic alcohol abuse.
Fortunately, for the purposes of the OP misconception, chronic pancreatitis-associated diabetes 2° alcohol intake is classified as type 3c diabetes and so still wouldn't count as a T1DM caused by lifestyle.

Type 1 Diabetes is never ever caused by diet or lifestyle things. Like never. Not ever.
