If I sell and reinvest 401k into infrastructure assets, am I making the wrong call?

Worried about inflation and devaluing dollar and want to reallocate away from total market index fund where 100% of my holdings are and reinvest the same into infrastructure assets which will hopefully help hedge the inflation risk.

I always hear I shouldn’t “time the market”. Is this considered the same thing or is this different considering I would be reinvesting and just reallocating to a different share class?
