Stimulus spending CAUSES inflation. You are expanding the money supply. You want to reduce prices, then you need to cool off the economy and reduce the money supply.
Lowering govt spending PLUS raising taxes would have been the way.
Stimulus spending can cause inflation, but doesn't do so necessarily. A cursory look at deficits and inflation charts will tell you as much. Biden got inflation under control and got the economy to bounce back very quickly -- a feat very few people believed he could pull off.
"Reducing prices" means deflation, which doesn't happen outside of a depression. Triggering a depression intentionally is absolutely bonkers in terms of policy.
