Can I keep more than 24h of local snapshots?

I use MacOS for work, from home. Company policy prevents me using Time Machine to do backups: preferences are greyed out in Settings.app and the text "These settings are controlled by a profile." appears in the button.

However I can and do use local snapshots, which I enabled with the command "sudo tmutil enable" (after granting my terminal full access in the "Privacy & Security" pane of Settings.app.).

I take snapshots every 4h using a cronjob that runs "tmutil localsnapshot" and my plan was to limit the total number of snapshots using another cronjob, but that appears to be unnecessary because I there are never any local snapshots older than 24h.

I restore files I've accidentally kludged about once a week, and would love to be able to go back a day or two instead of just a few hours. Does anyone know how to change the settings so I can keep more than 24h of local snapshots?

" would love to be able to go back a day or two " —This is the job of Time Machine.

Local snapshots are just that, and you have limited control, as this is baked into the macOS

Time Machine incorporates these backups automatically accordingly as 24 hr roll-around.

Really you have to do nothing but use Time Machine as intended..
