USART3 Remapping on PA13 PA14

[PL125]

Hi, I'm trying to remap USART3 to use pins PA13 and PA14 of a CH32V305FBP6, however it doesn't seem to be taking effect.

void UART_Config(uint32_t baudrate) {
    USART_InitTypeDef USART_InitStructure = {};
    GPIO_InitTypeDef  GPIO_InitStructure = {
        .GPIO_Speed = GPIO_Speed_50MHz,
    };

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO | RCC_APB2Periph_GPIOA, ENABLE);
    GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE);
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART3, ENABLE);

    GPIO_PinRemapConfig(GPIO_FullRemap_USART3, ENABLE);
    //GPIO_PinRemapConfig(GPIO_PartialRemap_USART3, ENABLE);
    //GPIO_PinRemapConfig(GPIO_PartialRemap1_USART3, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_14;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    USART_InitStructure.USART_BaudRate = baudrate;
    USART_InitStructure.USART_WordLength = USART_WordLength_8b;
    USART_InitStructure.USART_StopBits = USART_StopBits_1;
    USART_InitStructure.USART_Parity = USART_Parity_No;
    USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Tx | USART_Mode_Rx;

    USART_Init(USART3, &USART_InitStructure);

    USART_Cmd(USART3, ENABLE);
}

The (10b PA13 PA14) partial remapping function is not
supported for lot numbers where the fifth digit of
the lot number is less than 2 and the penultimate
sixth digit of the lot number is 0.
