Could I modify integration points for calculating elements

I'd like to modified integration points in Gaussian Quadrature, which is used for integrtion calculation of elements because in acoustics analysis it is knwon that simple modification of integration points produces higher accurte results than the case with same size elements with conventional integration points.
Please tell me the procedure for do it.
As references of Gaussian Quadrature and effects of modifying integration points in acoustcs analyses see belows. https://www.comsol.com/blogs/introduction-to-numerical-integration-and-gauss-points/ https://www.researchgate.net/publication/230677327_Application_of_modified_integration_rule_to_time-domain_finite-element_acoustic_simulation_of_rooms
