The flatband bandwidth minima angles are found to grow linearly with interlayer coupling {\\omega} and decrease with Fermi velocity. Application of moderate pressure values of up to 2.5 GPa achievable through a hydraulic press should allow accessing a flatband for angles as large as $\\sim 1.5$^{\\circ}$ instead of $\\sim 1 \\circ$ at zero pressure.
