No. Indirect costs on grants aren't some slush fund used to fund whatever but are real costs involved in doing science. It costs money to build lab facilities, maintain and repair lab equipment, pay salaries of support staff like IT folks and lab techs. If indirect costs get capped, more of the actual grant will have be used for these things and less science will get done.
Included in this overhead is administrative staff salaries and administration's facilities that researchers themselves have no control over. That's all spending controlled by research administrators and the institutions administrative layers that control research including decisions about who they hire for administrative roles and various aspects of strategic planning.
