Start blocking time as “tentative” in chunks, then when it gets too much adjust the chunk to fit the meetings you need / want to attend and set the rest to busy.

I’ve been doing that for the past few years I also usually have chunks set as busy for the morning end of day to make sure I get an orderly start and end of each day.

At least anecdotally my productivity has improved.

I get an hour at the start and end of each day to catch up and tie any loose ends to make things don’t fall between the cracks.

It really depends on your organization and workload tho so ymmv.
