Solved: Disabling Podcasts (Diabled, not just Disable for Managed Users) in PMS will remove podcasts like I wanted. Click your user icon in the top right of PMS, click Account, click Online Media Sources, then disable podcasts. Thanks to @x64man for the help.
The setting to remove podcasts from the home screen only removes the home screen row. It does not remove the library section icon or the icon in the sidebar. We should have the same ability to remove unwanted features as we do on other player apps. Also, please ensure toggling this also removes podcasts from search results.
