is there any way to download osx mavericks .dmg file?

A pre warning.

Do NOT look for any non-official sources for Mavericks. You can find illegal ways to purchase flash drives with every Mac or Windows OS on them via eBay, Amazon and who knows where else.

Apple did NOT create these. Not only are they illegal, as Apple still maintains the copyright on their software, but the user has no idea what may be on these drives that shouldn't be there. Like back doors, ransomware, key loggers, etc.

Apple has been inclined to keep older versions available for only so Loooong and then they are dropped

Another good example of dropping older version would macOS 10.13 High Sierra released in about 2017

You can get HS 10.13 if you jump through some hoops but Mavericks - no

Apple offers installers for all versions of Mac OS X / macOS from 10.7 ("Lion") to 15 ("Sequoia"), except for 10.9 (Mavericks). That one is missing for some unexplained reason.
