If you want to leave tech you should save up for 4-5 years of expenses to accomodate for under-employment, downsize your lifestyle to fit a household income under 80k, and then reskill in another field.
I have tried to move away incrementally from the tech industry by working less and consulting, and it is not effective. There's simply nothing else you can do that pays as well for so little effort. It draws you back in like a tarpit because there's always more work to do. Committing to a clean break and immersing yourself in a new field seems like the better approach.
