iOS 14: Call kit hide call history in recents

I am developing one application which has audio and video calling functionality and i m using callkit. By default it is displaying application call history in device phone book Recents tab. I want to hide callkit call history from device phone book. is there anyway to do it? setIncludesCallsInRecents = FALSE . this flag only works with iOS 12, is there any way to achieve this on iOS 13 and iOS 14

• (void)config {

CXProviderConfiguration *config = [[CXProviderConfiguration alloc]
initWithLocalizedName:[NSBundle.mainBundle objectForInfoDictionaryKey:@"CFBundleName"]];
config.ringtoneSound = @"notes_of_the_optimistic.caf";

Code Block 
 NSLog(@"config provider delegate");

config.supportsVideo = FALSE;

Code Block 
//config.supportsVideo = TRUE;

[config setIncludesCallsInRecents:FALSE];

Code Block 
config.iconTemplateImageData = UIImagePNGRepresentation([UIImage imageNamed:@"callkit_logo"]);

//NSArray *ar = @[ [NSNumber numberWithInt:(int)CXHandleTypeGeneric] ];

Code Block 
NSArray *ar = @[ [NSNumber numberWithInt:(int)CXHandleTypeGeneric] ];

NSSet *handleTypes = [[NSSet alloc] initWithArray:ar];
[config setSupportedHandleTypes:handleTypes];

Code Block 
//bhoomi
 [config setMaximumCallGroups:2];
[config setMaximumCallsPerCallGroup:1];

// [config setMaximumCallGroups:3];
//[config setMaximumCallsPerCallGroup:2];

Code Block 
self.provider = [[CXProvider alloc] initWithConfiguration:config];
[self.provider setDelegate:self queue:dispatch_get_main_queue()];
 [self.observer setDelegate:self queue:dispatch_get_main_queue()];

}
