Experiment Slowing down grass growth

I have hated mowing grass ever since I was a young man tasked with the job. I have blown up at least a dozen mowers spent endless hours trying to fix them and end up angry and smelling of gas, just the futility of it is maddening for myself wasting all this energy and time has never made sense to me. Years ago pre permaculture, I dreamt of killing all the grass and having maybe cement or some rocks lol, (my father actually did this at his house) while watching youtube videos I watched a gentleman misinterpret an idea and spread sawdust on his land for his row crops "surprise" nothing grew much there at all, it got me thinking I cannot be the only one who hates wasting time and resources mowing grass. My Hypothesis would be the sawdust(high carbon) locked up the nitrogen and massively slowed down the growth of his crops,
Experiment
spreading sawdust onto/into lawns could it slow down the grasses growth? eliminating maybe 50% of mowing? would equal less wasted hours and much less emissions hurting the earth and save everyone some money?
If this has been done or talked about or I'm in the wrong place feel free to remove this post, I'm new here thanks

What do you intend to do with the space once the grass is gone?
How large of a lawn do you have/are you trying to kill?

Tina - I don't think he is proposing killing grass, but essentially "anti-fertilising" it to slow the growth. High carbon mulching will reduce grass vigour through nitrogen leeching, but also switch the soil from bacterial to fungal systems.

My experience of spreading even deep woodchips to prepare beds for planting through is that some grass usually breaks through and survives, but usually a small enough area that I can hand pull a patch.

Thanks for the reply Tina and Michael, Michael is right on the money with the term "anti-fertilizing" my wife and I plan relatively soon 1-2years moving out of this house. For resale we are going to leave the grass and continue our gardens which is where I like to spend my time outside and not mowing grass. So if this sawdust experiment is effective I could have been doing it for years actually 14 years, and if that would save me 50% speculated mowing, it would save many many dozens of hours of work and running polluting inefficient mowers, this could also be effective for seniors and anyone not obsessed with lawn aesthetics.
