NITROGENATION OPTION
Disclaimer: Gas in any pressurized environment is a dangerous thing. Check the blowoffs of any pressurized equipment with the supplier before attempting anything outside its design spec.
Keg beer and build the carbonation level to 1.2 vol. (2.4 g/L) of CO2.
Add nitrogen. The method I would recommend for a home setup is to push nitrogen through a carbonation lid (a special lid with a sintered stone) on a Corny keg. Corny kegs can comfortably take 45 psi of nitrogen.
Bring the keg to 2.2 bar (32 psi) or as high as 3 bar (44 psi) if possible and allow the nitrogen to slowly dissolve. This takes some time, and without gas testing equipment, the pour is your only indication.
Pour at a top pressure of 38 psi (2.6 bar) through a creamer nozzle, ideally with nitrogen top pressure so as to avoid any further carbonation pickup. A full pint at 4–6°C (39–43°F) will take 2 minutes to settle and will have 10–15 mm (about 0.5”) of head depending on the shape of the glassware.
Send me a picture of said pint with plenty of details on how it’s drinking.
