Look in the settings of your camera app. If such an option exists, that's where it will be. Though at a quick glance my s21's camera doesn't have that option, so I don't think it's that likely.
Of course the naming system here is informative: that 14 digit number is yyyymmdd_hhmmss, i.e. a date+time stamp for the image. It's also pretty standard for Android: my Pixel 2 would prefix this time stamp with PXL_, while my 2010 HTC Desire would prefix it with IMG_, but using an ISO8601 datestamp in the filename rather than just a shutter release number (most likely what your Canon does) has been a common feature from the early days of Android.
A third party camera app may have other options. Open Camera allows you to choose the format of the date+time stamp, though it still saves images as IMG_date_time rather than IMG_SequenceNumber (you can change the "IMG_" prefix if you prefer). I don't know about others as it's years since I tried other alternative camera apps. Of course a third party app will have other imaging features, but as it's not written for a specific phone's camera hardware it may also not be able to use all of the features of your phone's camera system.
