Eating then sleeping , not moving much. “Graze” during the day and keep snacks close by and heavy cream Is always an answer
Can certainly double most of this. Adding cream in place of milk in coffee and sauces, lots of snacks: add a pastry to every large hot drinks. Have an open bowl of snacks at your desk, next to your sofa, on the bedside table and an open bag of something with you on transport.
Avoid prolonged exercise. If you want to exercise you can keep a healthier heart and stay strong with lifting. A simple (but not ideal) way of looking at gainer/feedee exercise is you should be aching after but not sweating during the exercise.
There is then the potentially controversial use of sugars (maltodextrin) as an insulin driver before meals. It’s not something I personally recommend but there’s a lot of info on it in the forums here.
